Hello,

You can simply use Loaded event of this control to get reference to the control instance using sender argument of the event handler.

which controls load event  should i use? In my case the grid contains a combobox and a combobox contains a radtree view.
I tried using the load event in various ways,but still its not working.

 private void ddlMultiselectcmb_Loaded(object sender, RoutedEventArgs e)
        {
            //Admin_usermanagmentServiceSoapClient svcSoapClient = new Admin_usermanagmentServiceSoapClient();
            //svcSoapClient.GetUserDetailsCompleted += new EventHandler<GetUserDetailsCompletedEventArgs>(svcSoapClient_GetUserDetailsCompleted);
            //svcSoapClient.GetUserDetailsAsync();

            //RadTreeView radTrv = (sender as RadTreeView);
            //RadTreeViewItem item1 = new RadTreeViewItem();
            //item1.Header = "Abhi";
            //RadTreeViewItem item2 = new RadTreeViewItem();
            //item1.Header = "Deepak";
            //radTrv.Items.Add(item1);
            //radTrv.Items.Add(item2);
            //sender = radTrv;
}



private void radgrdUserdetails_Loaded(object sender, RoutedEventArgs e)
        {
            //IList<RadTreeView> controls = radgrdUserdetails.ChildrenOfType<RadTreeView>();

            //RadTreeView radTrv = controls[0];
            //RadTreeViewItem item1 = new RadTreeViewItem();
            //item1.Header = "Abhi";
            //RadTreeViewItem item2 = new RadTreeViewItem();
            //item1.Header = "Deepak";
            //radTrv.Items.Add(item1);
            //radTrv.Items.Add(item2);
        }


I tried these 2 load events.....both of them are not working.

please suggest as what to be done......................
