Property Value

Type: System.Object
The value of the selected item.

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.

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.
