Examples
The following example binds a ListBox to a collection of Employee
objects. The example sets SelectedValuePath to @EmployeeNumber
and SelectedValue to 12345
. This selects the Employee
that has 12345
as the value of EmployeeNumber
. This example also binds a TextBlock to the SelectedValue of the ListBox. When the user changes the selection in the ListBox, the TextBlock is updated to show the employee number of the currently selected employee.
<XmlDataProvider x:Key="Employees" XPath="/Employees/*">
<x:XData>
<Employees xmlns="">
<Employee Name="Terry Adams" Type="FTE" EmployeeNumber="1" />
<Employee Name="Claire O'Donnell" Type="FTE" EmployeeNumber="12345" />
<Employee Name="Palle Peterson" Type="FTE" EmployeeNumber="5678" />
<Employee Name="Amy E. Alberts" Type="CSG" EmployeeNumber="99222" />
<Employee Name="Stefan Hesse" Type="Vendor" EmployeeNumber="-" />
</Employees>
</x:XData>
</XmlDataProvider>
<DataTemplate x:Key="EmployeeItemTemplate">
<TextBlock Text="{Binding XPath=@Name}" />
</DataTemplate>
<ListBox Name="employeeListBox"
ItemsSource="{Binding Source={StaticResource Employees}}"
ItemTemplate="{StaticResource EmployeeItemTemplate}"
SelectedValue="12345"
SelectedValuePath="@EmployeeNumber"/>
<TextBlock Text="{Binding ElementName=employeeListBox,
Path=SelectedValue}"/>
Remarks
The SelectedValuePath property specifies the path to the property that is used to determine the value of the SelectedValue property. Setting SelectedValue to a value X attempts to select an item whose value evaluates to X; if no such item can be found, the selection is cleared.
