#977 – DisplayMemberPath Indicates Property to Use for Displaying Bound Items

When you use data binding to bind an ItemsControl to a collection, there are several ways to control how each item in the list is rendered:

  • Rely on the ToString method of the bound item to generate a string to be displayed
  • Use a data template to create a more complex rendering of the item
  • Use the DisplayMemberPath property to indicate which property should be used in generating a string

DisplayMemberPath can be set to the name of a property (of type string) on the bound object.  The value of that property is then used as the displayed value of each item in the list.

Below, the KnownFor property of an Actor is used to generate the string in the ListBox.

        <ListBox Margin="15" Width="200" Height="150"
                 ItemsSource="{Binding ActorList}"
                 SelectedItem="{Binding SelectedActor}"/>
        <TextBlock Text="{Binding SelectedActor.FullName}"
                   HorizontalAlignment="Center" Margin="0,5"/>
