- Attributes
Examples
The following example shows a TreeView that uses a HierarchicalDataTemplate to display the EmployeeName
and EmployeeWorkDay
properties of an Employee
and sets the SelectedValue property to the EmployeeNumber
. When you select an EmployeeName
in the TreeView, the SelectedValue is set to the EmployeeNumber
.
<TreeView ItemsSource="{Binding Source={StaticResource myEmployeeData},
XPath=EmployeeInfo}"
Name="myTreeView"
SelectedValuePath="EmployeeNumber"
/>
<TextBlock Margin="10">SelectedValuePath: </TextBlock>
<TextBlock Margin="10,0,0,0"
Text="{Binding ElementName=myTreeView,
Path=SelectedValuePath}"
Foreground="Blue"/>
<TextBlock Margin="10">SelectedValue: </TextBlock>
<TextBlock Margin="10,0,0,0"
Text="{Binding ElementName=myTreeView,
Path=SelectedValue}"
Foreground="Blue"/>
Remarks
The SelectedValuePath property specifies the path to the property that is used to determine the value of the SelectedValue property. For example, assume that a TreeView is bound to a collection of objects of type Employee
, which has two properties called EmployeeName
and EmployeeNumber
. You can use a HierarchicalDataTemplate to display the value of EmployeeName
in the TreeView and set SelectedValuePath to "EmployeeNumber"
to have SelectedValue return the value of EmployeeNumber
.
