Issues with data binding in ItemContainerStyle in Silverlight 3

Question

I cannot use data binding in ItemContainerStylefor ListBoxin Silverlight 3. It works fine in WPF. This is a contrived example to demonstrate my problem. I really want to bind to a property IsSelected, but I think this example is easier to execute.

I have an object ListBoxrelated :ObservableCollection<Item>Item

public class Item {
  public String Name { get; }
  public Brush Color { get; }
}

Here is the corresponding Silverlight XAML:

<ListBox x:Name="listBox" ItemsSource="{Binding .}">
  <ListBox.ItemContainerStyle>
    <Style TargetType="ListBoxItem">
      <Setter Property="Background" Value="{Binding Color}"/>
    </Style>
  </ListBox.ItemContainerStyle>
  <ListBox.ItemTemplate>
    <DataTemplate>
      <TextBlock Text="{Binding Name}"/>
    </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>

The same XAML can be used in WPF if TargetType="ListBoxItem"replaced by TargetType="{x:Type ListBoxItem}".

WPF Color Item. Silverlight , XamlParseException AG_E_RUNTIME_MANAGED_UNKNOWN_ERROR. , XAML, , , :

  Binding binding = new Binding("Color");
  Setter setter = new Setter(ListBoxItem.BackgroundProperty, binding);
  Style style = new Style(typeof(ListBoxItem));
  style.Setters.Add(setter);
  listBox.ItemContainerStyle = style;

, ArgumentException Silverlight.
