    When I set my ItemSource for the TreeViewItem more than once I get this error.   I ran differant querys and set the ItemSource. Any idea what I'm doing wrong. I'm using RIA Services.  The first time it works fine.. the 2nd it errors out..
     Thanks again!!

    // Pass In _Topic...

      var query = from em in this.DS.GetEmailsQuery() where em.TOPIC == _Topic
           orderby em.EMAILDATE descending
                  select em;

        LoadOperation<Email> lo =  this.DS.Load(query); 
        lo.Completed += new EventHandler(lo_Get_Data_Completed_INBOX);




        void lo_Get_Data_Completed_INBOX(object sender, EventArgs e) 

           LoadOperation owlop = sender as LoadOperation;  
                   if (owlop.HasError)   
                        // do something


                    treeviewItem.ItemsSource = this.DS.Emails;     << ERROR HERE >>>

    Hi Jon The Nerd,

    We are not aware of such issue with RadTreeView. Can you try with the MS TreeView and let us know the result.

    I appears to only happen on IE on my computer.  Other computers don't have the error.
    thanks... I don't think it's the treeview - but maybe IE?
