I am trying to add a list of lists of lists to a radtreeView but the child elements never appear, I have used a HeirichalDataTemplate as a test for the first 2 elements, is there something I am missing , given the following xalm
<pre>
<telerik:RadTabItem Header="Lookup Sets">
<telerik:RadTreeView IsLoadOnDemandEnabled="True" ItemsSource="{Binding AttributeLookupSetConversions}">
<telerik:RadTreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type cm:AttributeLookupSetConversion}">
<CheckBox Content="{Binding Path=Name}" IsChecked="{Binding Path=IsSelected, Mode=TwoWay}" Checked="CheckBox_Checked" Unchecked="CheckBox_Unchecked" Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type telerikDocking:RadSplitContainer}}, Path=DataContext.UpdateSelectionCommand}"/>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type cm:AttributeConversion}">
<CheckBox Content="{Binding Path=Name}" IsChecked="{Binding Path=IsSelected, Mode=TwoWay}" Checked="CheckBox_Checked" Unchecked="CheckBox_Unchecked" Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type telerikDocking:RadSplitContainer}}, Path=DataContext.UpdateSelectionCommand}"/>
</HierarchicalDataTemplate>
</telerik:RadTreeView.Resources>
</telerik:RadTreeView>
</telerik:RadTabItem>
</pre>
I cant seem to get the UI to show its child elements
