Hi Alex, -  - It is important what you do in your code behind - the LoadOnDemand event handler of the RadTreeView. - In order to stop the animation, you have to set the IsLoadingOnDemand property to true like so: -  -  -  - private void radTreeView_LoadOnDemand(object sender, RadRoutedEventArgs e)  -         {  -             // get the treeview  -             Telerik.Windows.Controls.RadTreeView tree = sender as Telerik.Windows.Controls.RadTreeView;  -             // get the clicked Item  -             RadTreeViewItem clickedItem = e.OriginalSource as RadTreeViewItem;  -             // add the new items  -             RadTreeViewItem newItem = new RadTreeViewItem()  -             {  -                 Header = New Item -             };  -             clickedItem.Items.Add(newItem);  -             //System.Threading.Thread.Sleep(2000);  -             clickedItem.IsLoadingOnDemand = false;  -    -         } -  - Please let us know if this helps you or not. You can also provide a sample demosntrating your issue s that we could investigate in depth. -  - Regards, -  Petar Mladenov  - the Telerik team -  - Let us know about your Windows Phone 7 application built with RadControls and we will help you promote it.
