  I have a treeview with an attached context menu. The context menu items have commands which are pointing to the view model, like so (shortened version):
  

  <telerik:RadContextMenu.ContextMenu>    
        <telerik:RadContextMenu x:Name="ContextMenu" Opened="ContextMenuOpened">
            <telerik:RadMenuItem Header="Edit Group" Command="{Binding EditCommand}" Name="EditNode"/>
        </telerik:RadContextMenu>
</telerik:RadContextMenu.ContextMenu>

  
  Now what I'd like to do is set the current treeview item to IsInEditMode=true - basically like pressing F2, but raised by the context menu item click, and in a MVVM context.
  
  I can set my property from MVVM, but how to bind/reference the clicked tree view item?
  I suppose I should pass a command parameter but I just can't figure it out.
  
  Your help much appreciated - thx.

  Never mind, figured it out: Just raise an event (urgh..). Got it from here: http://blog.tonysneed.com/2011/01/28/tackling-the-problem-of-modal-dialogs-in-mvvm/

  Petar,
  
  thank you very much for looking into this. Your solution certainly makes for very streamlined code. I am using RIA services - would I have to add the IsInEditMode to all of my Entities definitions then?

  Hello Frankd,

   Yes, you will have to add a boolean property to your Entities classes or their wrapper classes.

  All the best,
