Silverlight 3 RadTreeListView HierarchicalDataTemplate Question

[Randall Anderson]

If I have the following data structure

    public class Level0
    {
        public class Level2
        {
            public string Level2Name { get; set; }
        };

        public class Level1
        {
            public string Level1Name { get; set; }
            public List<Level2> Level2List;
            public Level1()
            {
                Level2List = new List<Level2>();
            }
        };

        public string Level0Name { get; set; }
        public List<Level1> Level1List;

        public Level0()
        {
            Level1List = new List<Level1>();
        }
    }

And I want to define a HierarchicalDataTemplate for use in a RadTreeListView in silverlight 3.  I tried the following:

        <telerik:HierarchicalDataTemplate 
            x:Key="Level2Template" >
            <TextBlock Foreground="Yellow" Text="{Binding Level2name}"></TextBlock>
        </telerik:HierarchicalDataTemplate>

        <telerik:HierarchicalDataTemplate 
            x:Key="Level1Template" 
            ItemTemplate="{StaticResource Level2Template}"
            ItemsSource="{Binding Level2List}" >
            <TextBlock Foreground="Blue" Text="{Binding Level1Name}"></TextBlock>
        </telerik:HierarchicalDataTemplate>

        <telerik:HierarchicalDataTemplate 
            x:Key="Level0Template" 
            ItemTemplate="{StaticResource Level1Template}" 
            ItemsSource="{Binding Level1List}" >
            <TextBlock Foreground="Red" Text="{Binding Level0Name}"></TextBlock>
        </telerik:HierarchicalDataTemplate>

then the RadTreeListView

            <telerikNavigation:RadTreeListView
                x:Name="TheTree" 
                ItemTemplate="{StaticResource Level0Template}" >

                <telerikNavigation:RadTreeListView.Columns>
                    <telerikNavigation:RadColumn Header="Hierarchy" />
                </telerikNavigation:RadTreeListView.Columns>

</telerikNavigation:RadTreeListView>

I tried numerous variations on this and nothing seems to work to display the tree listview.
Can someone show me where the problem is or suggest better way.  I cant use Silveright 4 yet in this project.

solution: List needs to be property.  wow, i looked and looked and didnt notice this until a long time later.
