Property Value
Type: System.StringThe path used to get the SelectedValue. The default is an empty string.
The SelectedValuePath property specifies the path to the property that is used to determine the value of the SelectedValue property.
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.
