Hi,

this is my xamdatatree

<ig:XamDataTree DisplayMemberPath="NodeText" ItemsSource="{Binding Tree.Root.Children}">
    <ig:XamDataTree.SelectionSettings>
<ig:TreeSelectionSettings NodeSelection="Single"/>
</ig:XamDataTree.SelectionSettings>
<ig:XamDataTree.GlobalNodeLayouts>
<ig:NodeLayout Key="Nodes" TargetTypeName="INode" IsExpandedMemberPath="IsExpanded">
<ig:NodeLayout.ItemTemplate>
<DataTemplate>
  <StackPanel>
  <TextBlock .. />
  <Image ../>
</StackPanel>
</DataTemplate>
</ig:NodeLayout.ItemTemplate>
</ig:NodeLayout>
</ig:XamDataTree.GlobalNodeLayouts>
</ig:XamDataTree>

How can i disable the XamDataTreeNodes? I would like to bind it eg in the nodelayout

   <ig:NodeLayout Key="Nodes" TargetTypeName="INode" IsEnabledMemberPath="IsEnabled">

Thanks
