  hi
  Admin and everyone!
   i have problem about RadTreeview, can anybody give me a help?
  
  I generated a treeview by the way of data-binding. But the treeview's default status is collapsed. I want the treeview's status is expanded, what should i do?
   <Controls:ContainerBinding PropertyName="IsExpanded" Binding="{Binding IsExpanded,Mode=OneTime}" />
  by this way, i can do it, but i have to add one property IsExpanded to my customer object. there is another way?
  
  
  

  
  

  
  Anybody?
  best wishes
  thanks

  Hello Lee ,

   Indeed, the ContainerBindings solution is the typical MVVM/XAML solution for this scenario. One thing to note here is that in SL 5 you can use Style Bindings instead, just like in WPF.
  If you are looking for a code behind solution and you need to expand all RadTreeViewItems, you can use the ExpandAll() method of the RadTreeView. Is this suitable for you ?
