# How to: Use a Custom Context Menu with a TextBox
|
||||
This example shows how to define and implement a simple custom context menu for a <xref:System.Windows.Controls.TextBox>.
|
||||
|
||||
## Example
|
||||
## Define a Custom Context Menu
|
||||
The following [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] example defines a <xref:System.Windows.Controls.TextBox> control that includes a custom context menu.
|
||||
|
||||
The context menu is defined using a <xref:System.Windows.Controls.ContextMenu> element. The context menu itself consists of a series of <xref:System.Windows.Controls.MenuItem> elements and <xref:System.Windows.Controls.Separator> elements. Each <xref:System.Windows.Controls.MenuItem> element defines a command in the context menu; the <xref:System.Windows.Controls.HeaderedItemsControl.Header%2A> attribute defines the display text for the menu command, and the <xref:System.Windows.Controls.MenuItem.Click> attribute specifies a handler method for each menu item. The <xref:System.Windows.Controls.Separator> element simply causes a separating line to be rendered between the previous and subsequent menu items.

||||
|
||||
[!code-xaml[TextBox_ContextMenu#_TextBox_ContextMenuXAML](~/samples/snippets/csharp/VS_Snippets_Wpf/TextBox_ContextMenu/CSharp/Window1.xaml#_textbox_contextmenuxaml)]
|
||||
|
||||
## Example
|
||||
## Implement a Custom Context Menu
|
||||
The following example shows the implementation code for the preceding context menu definition, as well as the code that enables and disables the context menu. The <xref:System.Windows.Controls.ContextMenu.Opened> event is used to dynamically enable or disable certain commands depending on the current state of the <xref:System.Windows.Controls.TextBox>.
|
||||
|
||||
To restore the default context menu, use the <xref:System.Windows.DependencyObject.ClearValue%2A> method to clear the value of the <xref:System.Windows.FrameworkElement.ContextMenu%2A> property. To disable the context menu altogether, set the <xref:System.Windows.FrameworkElement.ContextMenu%2A> property to a null reference (`Nothing` in Visual Basic).

# How to: Use Spell Checking with a Context Menu
|
||||
By default, when you enable spell checking in an editing control like <xref:System.Windows.Controls.TextBox> or <xref:System.Windows.Controls.RichTextBox>, you get spell-checking choices in the context menu. For example, when users right-click a misspelled word, they get a set of spelling suggestions or the option to **Ignore All**. However, when you override the default context menu with your own custom context menu, this functionality is lost, and you need to write code to reenable the spell-checking feature in the context menu. The following example shows how to enable this on a <xref:System.Windows.Controls.TextBox>.
|
||||
|
||||
## Example
|
||||
## Define a Context Menu
|
||||
The following example shows the [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] that creates a <xref:System.Windows.Controls.TextBox> with some events that are used to implement the context menu.

# How to: Use the Image Element
|
||||
This example shows how to include images in an application by using the <xref:System.Windows.Controls.Image> element.
|
||||
|
||||
## Example
|
||||
## Define an image
|
||||
The following example shows how to render an image 200 pixels wide. In this [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] example, both attribute syntax and property tag syntax are used to define the image. For more information on attribute syntax and property syntax, see [Dependency Properties Overview](../advanced/dependency-properties-overview.md). A <xref:System.Windows.Media.Imaging.BitmapImage> is used to define the image's source data and is explicitly defined for the property tag syntax example. In addition, the <xref:System.Windows.Media.Imaging.BitmapImage.DecodePixelWidth%2A> of the <xref:System.Windows.Media.Imaging.BitmapImage> is set to the same width as the <xref:System.Windows.FrameworkElement.Width%2A> of the <xref:System.Windows.Controls.Image>. This is done to ensure that the minimum amount of memory is used rendering the image.

## Example
|
||||
## Position the cursor at the beginning
