#967 – ListBox Data Binding Basics, part IV

In the earlier posts, we created an Actor class and then populated a list with a series of Actor objects.  We can now bind a ListBox to this list using its ItemsSource property.

    <StackPanel>
        <ListBox Margin="15" Width="250" Height="250"
                 ItemsSource="{Binding ActorList}"
                 DisplayMemberPath="NameAndDates"
                 SelectedItem="{Binding SelectedActor}"/>
        <Label Margin="10,0" Content="{Binding SelectedActor.KnownFor}"/>
    </StackPanel>

The ItemsSource property indicates that we want the ListBox filled with elements from our ActorList property, which is a collection of Actor objects.

The DisplayMemberPath property indicates that each entry in the list should be rendered as a string using the Actor.NameAndDates property.

The SelectedItem property indicates that when a user selects an item, our SelectedActor property should be set to refer to the selected Actor instance.  We demonstrate that by binding a Label element to a property of that selected actor.
