    Im having problems with Hierarchical data Showing their children. 
    I had this working in the prior CTP and am now trying to make it work with the beta
    i dumbed up the code to see if i could figure out what was going on but still no child items are displayed.
    What am I doing wrong.

    Public Class Test
        Private _Items As New ObservableCollection(Of test)
        Public Property Items() As ObservableCollection(Of test)
                Return _Items
            End Get
            Set(ByVal value As ObservableCollection(Of test))
                _Items = value
            End Set
        End Property
        Private _Name As String = "AA"
        Public Property Name() As String
                Return _Name
            End Get
            Set(ByVal value As String)
                _Name = value
            End Set
        End Property
    End Class
    Private Sub tvKits_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles tvKits.Loaded
        Dim zz As New ObservableCollection(Of Test)
        zz.Add(New Test)
        zz(0).Items.Add(New Test)
        zz(0).Items(0).Items.Add(New Test)
        tvKits.ItemsSource = zz
    End Sub

    <telerikGridView:RadTreeListView IsReadOnly="True" x:Name="tvKits" Grid.Row="1"  Grid.Column="1" AutoGenerateColumns="False" >
                    <telerikData:PropertyRelation ParentPropertyName="Items"/>
            <telerikGridView:GridViewDataColumn Header="Assembly"  DataMemberBinding="{Binding Name}"  />
