Hi..
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.

HI..
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?
