 # How to: Add Custom Information to a TreeView or ListView Control (Windows Forms)
+
 You can create a derived node in a Windows Forms <xref:System.Windows.Forms.TreeView> control or a derived item in a <xref:System.Windows.Forms.ListView> control. Derivation allows you to add any fields you require, as well as custom methods and constructors for handling them. One use of this feature is to attach a Customer object to each tree node or list item. The examples here are for a <xref:System.Windows.Forms.TreeView> control, but the same approach can be used for a <xref:System.Windows.Forms.ListView> control.

 # How to: Bind Data to the Windows Forms DataGridView Control Using the Designer
+
 You can use the designer to connect a <xref:System.Windows.Forms.DataGridView> control to data sources of several different varieties, including databases, business objects, or Web services. When you bind the control to a data source using the designer, the control is automatically bound to a <xref:System.Windows.Forms.BindingSource> component that represents the data source. Additionally, columns are automatically generated in the control to match the schema information provided by the data source.

 After columns have been generated, you can modify them to meet your needs. For example, you can remove or hide columns you are not interested in displaying, you can rearrange the columns, or you can modify the column types. For more information about modifying columns, see the topics listed in the See Also section.

- You can also bind multiple <xref:System.Windows.Forms.DataGridView> controls to related tables to create master/detail relationships. In this configuration, one control displays a parent table and another control displays only those rows from a child table that are related to the current row in the parent table.

 # Considerations When Hosting an ActiveX Control on a Windows Form
+
 Although Windows Forms have been optimized to host Windows Forms controls, you can still use ActiveX controls. Keep the following considerations in mind when planning an application that uses ActiveX controls:  
  
 - **Security** The common language runtime has been enhanced with regard to code access security. Applications featuring Windows Forms can run in a fully trusted environment without issue and in a semi-trusted environment with most of the functionality accessible. Windows Forms controls can be hosted in a browser with no complications. However, ActiveX controls on Windows Forms cannot take advantage of these security enhancements. Running an ActiveX control requires unmanaged code permission, which is set with the <xref:System.Security.Permissions.SecurityPermissionAttribute.UnmanagedCode%2A?displayProperty=nameWithType> property. For more information about security and unmanaged code permission, see <xref:System.Security.Permissions.SecurityPermissionAttribute>.  
@@ -17,15 +18,14 @@ Although Windows Forms have been optimized to host Windows Forms controls, you c
 - **Total Cost of Ownership** ActiveX controls added to a Windows Form are deployed with that Windows Form in their entirety, which can add significantly to the size of the file(s) created. Additionally, using ActiveX controls on Windows Forms requires writing to the registry. This is more invasive to a user's computer than Windows Forms controls, which do not require this.  
  
    > [!NOTE]
-    > Working with an ActiveX control requires the use of a COM interop wrapper. For more information, see [COM Interoperability in Visual Basic and Visual C#](https://docs.microsoft.com/dotnet/visual-basic/programming-guide/com-interop/com-interoperability-in-net-framework-applications).

    > [!NOTE]
    > If the name of a member of the ActiveX control matches a name defined in the .NET Framework, then the ActiveX Control Importer will prefix the member name with **Ctl** when it creates the <xref:System.Windows.Forms.AxHost> derived class. For example, if your ActiveX control has a member named **Layout**, it is renamed **CtlLayout** in the AxHost-derived class because the **Layout** event is defined within the .NET Framework.

 The .NET Framework gives you power to develop and implement new controls. In addition to the familiar user control, you will now find that you are able to write custom controls that perform their own painting, and are even able to extend the functionality of existing controls through inheritance. Deciding which type of control to create can be confusing. This section highlights the differences between the various types of controls from which you can inherit, and gives considerations regarding the type to choose for your project.

 # DataGridView Control Technology Summary (Windows Forms)
+
 This topic summarizes information about the `DataGridView` control and the classes that support its use.

 User interface (UI) designers frequently find it necessary to display tabular data to users. The .NET Framework provides several ways to show data in a table or grid. The `DataGridView` control represents the latest evolution of this technology for Windows Forms applications.  
  
 The `DataGridView` control can display rows of data from a data store. Many types of data stores are supported. The data store can hold simple, untyped data, such as a one-dimensional array, or it can hold typed data, such as a <xref:System.Data.DataSet>.

 You can extend the `DataGridView` control in several ways to build custom behavior into your applications. For example, you can programmatically specify your own sorting algorithms, and you can create your own types of cells. You can easily customize the appearance of the `DataGridView` control by choosing among several properties. Many types of data stores can be used as a data source, or the `DataGridView` control can operate without a data source bound to it.  
  
 ## Implementing DataGridView Classes  
+
 There are several ways for you to take advantage of the `DataGridView` control's extensibility features. You can customize many aspects of the control through events and properties, but some customizations require you to create new classes derived from existing `DataGridView` classes.  
  
 The most typically used base classes are `DataGridViewCell` and `DataGridViewColumn`. You can derive your own cell class from `DataGridViewCell` or any of its child classes. Although you can add any cell type to any column, you will typically also derive a companion column class from `DataGridViewColumn` that hosts cells of your custom cell type by default.

+For an overview of properties, see [Properties Overview](/previous-versions/visualstudio/visual-studio-2013/65zdfbdt(v=vs.120)). There are a few important considerations when defining a property:  
  
- You must apply attributes to the properties you define. Attributes specify how the designer should display a property. For details, see [Design-Time Attributes for Components](https://docs.microsoft.com/previous-versions/visualstudio/visual-studio-2013/tk67c2t8(v=vs.120)).

 - If changing the property affects the visual display of the control, call the <xref:System.Windows.Forms.Control.Invalidate%2A> method (that your control inherits from <xref:System.Windows.Forms.Control>) from the `set` accessor. <xref:System.Windows.Forms.Control.Invalidate%2A> in turn calls the <xref:System.Windows.Forms.Control.OnPaint%2A> method, which redraws the control. Multiple calls to <xref:System.Windows.Forms.Control.Invalidate%2A> result in a single call to <xref:System.Windows.Forms.Control.OnPaint%2A> for efficiency.  
  
 - The .NET Framework class library provides type converters for common data types such as integers, decimal numbers, Boolean values, and others. The purpose of a type converter is generally to provide string-to-value conversion (from string data to other data types). Common data types are associated with default type converters that convert values into strings and strings into the appropriate data types. If you define a property that is a custom (that is, nonstandard) data type, you will have to apply an attribute that specifies the type converter to associate with that property. You can also use an attribute to associate a custom UI type editor with a property. A UI type editor provides a user interface for editing a property or data type. A color picker is an example of a UI type editor. Examples of attributes are given at the end of this topic.  
  
    > [!NOTE]

 For control authors, the .NET Framework provides a wealth of control authoring technology. Authors are no longer limited to designing composite controls that act as a collection of preexisting controls. Through inheritance, you can create your own controls from preexisting composite controls or preexisting Windows Forms controls. You can also design your own controls that implement custom painting. These options enable a great deal of flexibility to the design and functionality of the visual interface. To take advantage of these features, you should be familiar with object-based programming concepts.

 # Events in Windows Forms Controls
+
 A Windows Forms control inherits more than sixty events from <xref:System.Windows.Forms.Control?displayProperty=nameWithType>. These include the <xref:System.Windows.Forms.Control.Paint> event, which causes a control to be drawn, events related to displaying a window, such as the <xref:System.Windows.Forms.Control.Resize> and <xref:System.Windows.Forms.Control.Layout> events, and low-level mouse and keyboard events. Some low-level events are synthesized by <xref:System.Windows.Forms.Control> into semantic events such as <xref:System.Windows.Forms.Control.Click> and <xref:System.Windows.Forms.Control.DoubleClick>. For details about inherited events, see <xref:System.Windows.Forms.Control>.  
  
- If your custom control needs to override inherited event functionality, override the inherited `On`*EventName* method instead of attaching a delegate. If you are not familiar with the event model in the .NET Framework, see [Raising Events from a Component](https://docs.microsoft.com/previous-versions/visualstudio/visual-studio-2013/sh2e3k5z(v=vs.120)).

 # How to: Freeze Columns in the Windows Forms DataGridView Control Using the Designer
+
 When users view data displayed in a Windows Forms <xref:System.Windows.Forms.DataGridView> control, they sometimes need to refer to a single column or set of columns frequently. For example, when you display a table of customer information that contains many columns, it is useful for you to display the customer name at all times while enabling other columns to scroll outside the visible region.

 To achieve this behavior, you can freeze columns in the control. When you freeze a column, all the columns to its left (or to its right in right-to-left language scripts) are frozen as well. Frozen columns remain in place while all other columns can scroll. If column reordering is enabled, the frozen columns are treated as a group distinct from the unfrozen columns. Users can reposition columns in either group, but they cannot move a column from one group to the other.

 # How to: Apply Attributes in Windows Forms Controls
+
 To develop components and controls that interact correctly with the design environment and execute correctly at run time, you need to apply attributes correctly to classes and members.  
  
 ## Example  
+
 The following code example demonstrates how to use several attributes on a custom control. The control demonstrates a simple logging capability. When the control is bound to a data source, it displays the values sent by the data source in a <xref:System.Windows.Forms.DataGridView> control. If a value exceeds the value specified by the `Threshold` property, a `ThresholdExceeded` event is raised.  
  
 The `AttributesDemoControl` logs values with a `LogEntry` class. The `LogEntry` class is a template class, which means it is parameterized on the type that it logs. For example, if the `AttributesDemoControl` is logging values of type `float`, each `LogEntry` instance is declared and used as follows.

 The following sample shows the code for `FirstControl`. The control is enclosed in the namespace `CustomWinControls`. A namespace provides a logical grouping of related types. You can create your control in a new or existing namespace.

 The following procedures demonstrate basic formatting of cell values using the <xref:System.Windows.Forms.DataGridView.DefaultCellStyle%2A> property of a <xref:System.Windows.Forms.DataGridView> control and of specific columns in a control. For information about advanced data formatting, see [How to: Customize Data Formatting in the Windows Forms DataGridView Control](how-to-customize-data-formatting-in-the-windows-forms-datagridview-control.md).

 # How to: Iterate Through All Nodes of a Windows Forms TreeView Control

 It is sometimes useful to examine every node in a Windows Forms <xref:System.Windows.Forms.TreeView> control in order to perform some calculation on the node values. This operation can be done using a recursive procedure (recursive method in C# and C++) that iterates through each node in each collection of the tree.  
  
 Each <xref:System.Windows.Forms.TreeNode> object in a tree view has properties that you can use to navigate the tree view: <xref:System.Windows.Forms.TreeNode.FirstNode%2A>, <xref:System.Windows.Forms.TreeNode.LastNode%2A>, <xref:System.Windows.Forms.TreeNode.NextNode%2A>, <xref:System.Windows.Forms.TreeNode.PrevNode%2A>, and <xref:System.Windows.Forms.TreeNode.Parent%2A>. The value of the <xref:System.Windows.Forms.TreeNode.Parent%2A> property is the parent node of the current node. The child nodes of the current node, if there are any, are listed in its <xref:System.Windows.Forms.TreeNode.Nodes%2A> property.

 The <xref:System.ComponentModel.BackgroundWorker> component replaces and adds functionality to the <xref:System.Threading> namespace; however, the <xref:System.Threading> namespace is retained for both backward compatibility and future use, if you choose. For more information, see [BackgroundWorker Component Overview](backgroundworker-component-overview.md).

- Windows Forms uses the single-threaded apartment (STA) model because Windows Forms is based on native Win32 windows that are inherently apartment-threaded. The STA model implies that a window can be created on any thread, but it cannot switch threads once created, and all function calls to it must occur on its creation thread. Outside Windows Forms, classes in the .NET Framework use the free threading model. For information about threading in the .NET Framework, see [Threading](https://docs.microsoft.com/dotnet/standard/threading/index).

 # How to: Validate Data in the Windows Forms DataGridView Control
+
 The following code example demonstrates how to validate data entered by a user into a <xref:System.Windows.Forms.DataGridView> control. In this example, the <xref:System.Windows.Forms.DataGridView> is populated with rows from the `Customers` table of the Northwind sample database. When the user edits a cell in the `CompanyName` column, its value is tested for validity by checking that it is not empty. If the event handler for the <xref:System.Windows.Forms.DataGridView.CellValidating> event finds that the value is an empty string, the <xref:System.Windows.Forms.DataGridView> prevents the user from exiting the cell until a non-empty string is entered.

 # Implementing Virtual Mode with Just-In-Time Data Loading in the Windows Forms DataGridView Control
+
 One reason to implement virtual mode in the <xref:System.Windows.Forms.DataGridView> control is to retrieve data only as it is needed. This is called *just-in-time data loading*.  
  
 If you are working with a very large table in a remote database, for example, you might want to avoid startup delays by retrieving only the data that is necessary for display and retrieving additional data only when the user scrolls new rows into view. If the client computers running your application have a limited amount of memory available for storing data, you might also want to discard unused data when retrieving new values from the database.

 ## The Form  
+
 The following code example defines a form containing a read-only <xref:System.Windows.Forms.DataGridView> control that interacts with a `Cache` object through a <xref:System.Windows.Forms.DataGridView.CellValueNeeded> event handler. The `Cache` object manages the locally stored values and uses a `DataRetriever` object to retrieve values from the Orders table of the sample Northwind database. The `DataRetriever` object, which implements the `IDataPageRetriever` interface required by the `Cache` class, is also used to initialize the <xref:System.Windows.Forms.DataGridView> control rows and columns.  
  
 The `IDataPageRetriever`, `DataRetriever`, and `Cache` types are described later in this topic.

 ## The IDataPageRetriever Interface  
+
 The following code example defines the `IDataPageRetriever` interface, which is implemented by the `DataRetriever` class. The only method declared in this interface is the `SupplyPageOfData` method, which requires an initial row index and a count of the number of rows in a single page of data. These values are used by the implementer to retrieve a subset of data from a data source.  
  
 A `Cache` object uses an implementation of this interface during construction to load two initial pages of data. Whenever an uncached value is needed, the cache discards one of these pages and requests a new page containing the value from the `IDataPageRetriever`.

 ## The DataRetriever Class  
+
 The following code example defines the `DataRetriever` class, which implements the `IDataPageRetriever` interface to retrieve pages of data from a server. The `DataRetriever` class also provides `Columns` and `RowCount` properties, which the <xref:System.Windows.Forms.DataGridView> control uses to create the necessary columns and to add the appropriate number of empty rows to the <xref:System.Windows.Forms.DataGridView.Rows%2A> collection. Adding the empty rows is necessary so that the control will behave as though it contains all the data in the table. This means that the scroll box in the scroll bar will have the appropriate size, and the user will be able to access any row in the table. The rows are filled by the <xref:System.Windows.Forms.DataGridView.CellValueNeeded> event handler only when they are scrolled into view.

The `Cache` class defines an inner `DataPage` structure, which contains a <xref:System.Data.DataTable> to store the values in a single cache page and which calculates the row indexes that represent the upper and lower boundaries of the page.  
  
 The `Cache` class loads two pages of data at construction time. Whenever the <xref:System.Windows.Forms.DataGridView.CellValueNeeded> event requests a value, the `Cache` object determines if the value is available in one of its two pages and, if so, returns it.

 ## Additional Considerations  
+
 The previous code examples are provided as a demonstration of just-in-time data loading. You will need to modify the code for your own needs to achieve maximum efficiency. At minimum, you will need to choose an appropriate value for the number of rows per page of data in the cache. This value is passed into the `Cache` constructor. The number of rows per page should be no less than the number of rows that can be displayed simultaneously in your <xref:System.Windows.Forms.DataGridView> control.  
  
 For best results, you will need to conduct performance testing and usability testing to determine the requirements of your system and your users. Several factors that you will need to take into consideration include the amount of memory in the client machines running your application, the available bandwidth of the network connection used, and the latency of the server used. The bandwidth and latency should be determined at times of peak usage.

 # Property-Changed Events
-If you want your control to send notifications when a property named *PropertyName* changes, define an event named *PropertyName*`Changed` and a method named `On`*PropertyName*`Changed` that raises the event. The naming convention in Windows Forms is to append the word *Changed* to the name of the property. The associated event delegate type for property-changed events is <xref:System.EventHandler>, and the event data type is <xref:System.EventArgs>. The base class <xref:System.Windows.Forms.Control> defines many property-changed events, such as <xref:System.Windows.Forms.Control.BackColorChanged>, <xref:System.Windows.Forms.Control.BackgroundImageChanged>, <xref:System.Windows.Forms.Control.FontChanged>, <xref:System.Windows.Forms.Control.LocationChanged>, and others. For background information about events, see [Events](https://docs.microsoft.com/dotnet/standard/events/index) and [Events in Windows Forms Controls](events-in-windows-forms-controls.md).

 Property-changed events are useful because they allow consumers of a control to attach event handlers that respond to the change. If your control needs to respond to a property-changed event that it raises, override the corresponding `On`*PropertyName*`Changed` method instead of attaching a delegate to the event. A control typically responds to a property-changed event by updating other properties or by redrawing some or all of its drawing surface.

 # How to: Raise Change Notifications Using a BindingSource and the INotifyPropertyChanged Interface
+
 The <xref:System.Windows.Forms.BindingSource> component automatically detects changes in a data source when the type contained in the data source implements <xref:System.ComponentModel.INotifyPropertyChanged> and raises <xref:System.ComponentModel.INotifyPropertyChanged.PropertyChanged> events when a property value is changed. This change detection is useful because controls bound to the <xref:System.Windows.Forms.BindingSource> automatically update as the data source values change.  
  
 > [!NOTE]
 > If your data source implements <xref:System.ComponentModel.INotifyPropertyChanged> and you are performing asynchronous operations, you should not make changes to the data source on a background thread. Instead, you should read the data on a background thread and merge the data into a list on the UI thread.  
  
 ## Example  
+
 The following code example demonstrates a simple implementation of the <xref:System.ComponentModel.INotifyPropertyChanged> interface. It also shows how the <xref:System.Windows.Forms.BindingSource> automatically passes a data source change to a bound control when the <xref:System.Windows.Forms.BindingSource> is bound to a list of the <xref:System.ComponentModel.INotifyPropertyChanged> type.  
  
- If you use the `CallerMemberName` attribute, calls to the `NotifyPropertyChanged` method don't have to specify the property name as a string argument. For more information, see [Caller Information (C#)](https://docs.microsoft.com/dotnet/csharp/language-reference/attributes/caller-information) or [Caller Information (Visual Basic)](https://docs.microsoft.com/dotnet/visual-basic/programming-guide/concepts/caller-information).

 # Rendering a Windows Forms Control

 Rendering refers to the process of creating a visual representation on a user's screen. Windows Forms uses GDI (the new Windows graphics library) for rendering. The managed classes that provide access to GDI are in the <xref:System.Drawing?displayProperty=nameWithType> namespace and its subnamespaces.

 ## Drawing Functionality Provided by Control  
- The base class <xref:System.Windows.Forms.Control> provides drawing functionality through its <xref:System.Windows.Forms.Control.Paint> event. A control raises the <xref:System.Windows.Forms.Control.Paint> event whenever it needs to update its display.

These objects are shown in bold in the following code fragment.

 While <xref:System.Windows.Forms.Control.OnPaintBackground%2A> has an event-like nomenclature and takes the same argument as the `OnPaint` method, <xref:System.Windows.Forms.Control.OnPaintBackground%2A> is not a true event method. There is no `PaintBackground` event and <xref:System.Windows.Forms.Control.OnPaintBackground%2A> does not invoke event delegates. When overriding the <xref:System.Windows.Forms.Control.OnPaintBackground%2A> method, a derived class is not required to invoke the <xref:System.Windows.Forms.Control.OnPaintBackground%2A> method of its base class.  
  
 ## GDI+ Basics  
+
 The <xref:System.Drawing.Graphics> class provides methods for drawing various shapes such as circles, triangles, arcs, and ellipses, as well as methods for displaying text. The <xref:System.Drawing?displayProperty=nameWithType> namespace and its subnamespaces contain classes that encapsulate graphics elements such as shapes (circles, rectangles, arcs, and others), colors, fonts, brushes, and so on. For more information about GDI, see [Using Managed Graphics Classes](../advanced/using-managed-graphics-classes.md). The essentials of GDI are also described in the [How to: Create a Windows Forms Control That Shows Progress](how-to-create-a-windows-forms-control-that-shows-progress.md).  
  
 ## Geometry of the Drawing Region  
+
 The <xref:System.Windows.Forms.Control.ClientRectangle%2A> property of a control specifies the rectangular region available to the control on the user's screen, while the <xref:System.Windows.Forms.PaintEventArgs.ClipRectangle%2A> property of <xref:System.Windows.Forms.PaintEventArgs> specifies the area that is actually painted. (Remember that painting is done in the <xref:System.Windows.Forms.Control.Paint> event method that takes a <xref:System.Windows.Forms.PaintEventArgs> instance as its argument). A control might need to paint only a portion of its available area, as is the case when a small section of the control's display changes. In those situations, a control developer must compute the actual rectangle to draw in and pass that to <xref:System.Windows.Forms.Control.Invalidate%2A>. The overloaded versions of <xref:System.Windows.Forms.Control.Invalidate%2A> that take a <xref:System.Drawing.Rectangle> or <xref:System.Drawing.Region> as an argument use that argument to generate the <xref:System.Windows.Forms.PaintEventArgs.ClipRectangle%2A> property of <xref:System.Windows.Forms.PaintEventArgs>.  
  
 The following code fragment shows how the `FlashTrackBar` custom control computes the rectangular area to draw in. The `client` variable denotes the <xref:System.Windows.Forms.PaintEventArgs.ClipRectangle%2A> property.

 # How to: Sort and Filter ADO.NET Data with the Windows Forms BindingSource Component

 You can expose the sorting and filtering capability of <xref:System.Windows.Forms.BindingSource> control through the <xref:System.Windows.Forms.BindingSource.Sort%2A> and <xref:System.Windows.Forms.BindingSource.Filter%2A> properties. You can apply simple sorting when the underlying data source is an <xref:System.ComponentModel.IBindingList>, and you can apply filtering and advanced sorting when the data source is an <xref:System.ComponentModel.IBindingListView>. The <xref:System.Windows.Forms.BindingSource.Sort%2A> property requires standard ADO.NET syntax: a string representing the name of a column of data in the data source followed by `ASC` or `DESC` to indicate whether the list should be sorted in ascending or descending order. You can set advanced sorting or multiple-column sorting by separating each column with a comma separator. The <xref:System.Windows.Forms.BindingSource.Filter%2A> property takes a string expression.

-The Windows Forms <xref:System.Windows.Forms.Timer> is a component that raises an event at regular intervals. This component is designed for a Windows Forms environment. If you need a timer that is suitable for a server environment, see [Introduction to Server-Based Timers](https://docs.microsoft.com/previous-versions/visualstudio/visual-studio-2008/tb9yt5e6(v=vs.90)).

If you need a timer that is suitable for a server environment, see [Introduction to Server-Based Timers](/previous-versions/visualstudio/visual-studio-2008/tb9yt5e6(v=vs.90)).  
  
 ## Key Properties, Methods, and Events  
+
 The length of the intervals is defined by the <xref:System.Windows.Forms.Timer.Interval%2A> property, whose value is in milliseconds. When the component is enabled, the <xref:System.Windows.Forms.Timer.Tick> event is raised every interval. This is where you would add code to be executed. For more information, see [How to: Run Procedures at Set Intervals with the Windows Forms Timer Component](run-procedures-at-set-intervals-with-wf-timer-component.md). The key methods of the <xref:System.Windows.Forms.Timer> component are <xref:System.Windows.Forms.Timer.Start%2A> and <xref:System.Windows.Forms.Timer.Stop%2A>, which turn the timer on and off. When the timer is switched off, it resets; there is no way to pause a <xref:System.Windows.Forms.Timer> component.

 # Varieties of Custom Controls
+
 With the .NET Framework, you can develop and implement new controls. You can extend the functionality of the familiar user control as well as existing controls through inheritance. You can also write custom controls that perform their own painting.  
  
 Deciding which kind of control to create can be confusing. This topic highlights the differences among the various kinds of controls from which you can inherit, and provides you with information about how to choose a particular kind of control for your project.

 ## Kinds of Controls  
+
 Windows Forms supports three kinds of user-defined controls: *composite*, *extended*, and *custom*. The following sections describe each kind of control and give recommendations for choosing the kind to use in your projects.  
  
 ### Composite Controls  
+
 A composite control is a collection of Windows Forms controls encapsulated in a common container. This kind of control is sometimes called a *user control*. The contained controls are called *constituent controls*.  
  
 A composite control holds all of the inherent functionality associated with each of the contained Windows Forms controls and enables you to selectively expose and bind their properties.

 ### Extended Controls

 You can derive an inherited control from any existing Windows Forms control. With this approach, you can retain all of the inherent functionality of a Windows Forms control, and then extend that functionality by adding custom properties, methods, or other features. With this option, you can override the base control's paint logic, and then extend its user interface by changing its appearance.

 ### ActiveX Controls  
+
 Although the Windows Forms infrastructure has been optimized to host Windows Forms controls, you can still use ActiveX controls. There is support for this task in Visual Studio. For more information, see [How to: Add ActiveX Controls to Windows Forms](how-to-add-activex-controls-to-windows-forms.md).  
  
 ### Windowless Controls  
+
 The Microsoft Visual Basic® 6.0and ActiveX technologies support *windowless* controls. Windowless controls are not supported in Windows Forms.  
  
 ## Custom Design Experience  
+
 If you need to implement a custom design-time experience, you can author your own designer. For composite controls, derive your custom designer class from the <xref:System.Windows.Forms.Design.ParentControlDesigner> or the <xref:System.Windows.Forms.Design.DocumentDesigner> classes. For extended and custom controls, derive your custom designer class from the <xref:System.Windows.Forms.Design.ControlDesigner> class.
