How to: Create Simple or Complex TreeViews
This example shows how to create simple or complex xref:System.Windows.Controls.TreeView controls.
A xref:System.Windows.Controls.TreeView consists of a hierarchy of xref:System.Windows.Controls.TreeViewItem controls, which can contain simple text strings and also more complex content, such as xref:System.Windows.Controls.Button controls or a xref:System.Windows.Controls.StackPanel with embedded content. You can explicitly define the xref:System.Windows.Controls.TreeView content or a data source can provide the content. This topic provides examples of these concepts.
Example
The xref:System.Windows.Controls.HeaderedItemsControl.Header%2A property of the xref:System.Windows.Controls.TreeViewItem contains the content that the xref:System.Windows.Controls.TreeView displays for that item. A xref:System.Windows.Controls.TreeViewItem can also have xref:System.Windows.Controls.TreeViewItem controls as its child elements and you can define these child elements by using the xref:System.Windows.Controls.ItemsControl.Items%2A property.
The following example shows how to explicitly define xref:System.Windows.Controls.TreeViewItem content by setting the xref:System.Windows.Controls.HeaderedItemsControl.Header%2A property to a text string.

The following example show how to define child elements of a xref:System.Windows.Controls.TreeViewItem by defining xref:System.Windows.Controls.ItemsControl.Items%2A that are xref:System.Windows.Controls.Button controls.

The following example shows how to create a xref:System.Windows.Controls.TreeView where an xref:System.Windows.Data.XmlDataProvider provides xref:System.Windows.Controls.TreeViewItem content and a xref:System.Windows.HierarchicalDataTemplate defines the appearance of the content.

The following example shows how to create a xref:System.Windows.Controls.TreeView where the xref:System.Windows.Controls.TreeViewItem content contains xref:System.Windows.Controls.DockPanel controls that have embedded content.
