However, because the SelectedValuePath of this TreeView is set to EmployeeNumber, the SelectedValue is set to the EmployeeNumber. When you select an EmployeeName in the TreeView, the SelectedItem property returns the EmployeeInfo data item that corresponds to the selected EmployeeName. Obviously, this article aims at intermediate and advanced WPF users. I do not discuss MVVM here since tons of information can be found on the web. Each node can then have child nodes, and the child nodes can have child nodes and so on. The following example shows a TreeView that uses the previously defined HierarchicalDataTemplate and that sets the SelectedValue property to the EmployeeNumber. For example: Simplifying the WPF TreeView by Using the ViewModel Pattern I use TreeView + HierarchicalDataTemplate with multi-level binding because it is one of the least understood XAML binding topics. CSS3 HTML5 JavaScript jQuery PHP5 The TreeView control: TreeView introduction The TreeView control enabled you to display hierarchical data, with each piece of data represented by a node in the tree.

The examples in this topic illustrate this concept. Im hoping to do something like this but the items are displayed as empty headers. The SelectedValuePath property specifies the path to the property that is used to determine the value of the SelectedValue property. Im adding TreeViewItems manually in code behind and would like to use a DataTemplate to display them but cant figure out how to. The SelectedItem represents an object in the Items collection and the TreeView displays the value of a single property of the selected item. The SelectedValuePath property provides a way to specify a SelectedValue for the SelectedItem in a TreeView. This example shows how to use the SelectedValue and SelectedValuePath properties to specify a value for the SelectedItem of a TreeView. As we talked about in the previous article, the WPF TreeView can be used in a very simple manner, by adding TreeViewItem objects to it, either from Code-behind or simply by declaring them directly in your XAML.
