    Hi

    I've worked a bit with your TreeView and I'm suffering from one "little" issue.

    I was playing with Drag & Drop and sometime my application freeze (in facts, it disapears leaving my test page completely blank)

    I looked to exceptions and I found one but I'm not sure that it's the one which freeze the application.

    Here is the StackTrace :
       at Telerik.Windows.Controls.RadTreeViewItem.PrepareContainerForItemOverride(DependencyObject element, Object item)
       at System.Windows.Controls.ItemsControl.UpdateContainerForItem(Int32 index)
       at System.Windows.Controls.ItemsControl.OnCollectionChanged(Object sender, NotifyCollectionChangedEventArgs e)
       at System.Collections.Specialized.NotifyCollectionChangedEventHandler.Invoke(Object sender, NotifyCollectionChangedEventArgs e)
       at System.Collections.ObjectModel.ObservableCollection`1.OnCollectionChanged(NotifyCollectionChangedEventArgs e)
       at System.Collections.ObjectModel.ObservableCollection`1.InsertItem(Int32 index, T item)
       at System.Collections.ObjectModel.Collection`1.Add(T item)
       at System.Collections.ObjectModel.Collection`1.System.Collections.IList.Add(Object value)
       at Telerik.Windows.Controls.RadTreeView.EndDrag()
       at Telerik.Windows.Controls.RadTreeView.HandleMouseUp(MouseEventArgs e)
       at Telerik.Windows.Controls.RadTreeView.RadTreeView_MouseLeftButtonUp(Object sender, MouseEventArgs e)
       at System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
       at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)

    Hope that you'll be able to help me !

    Thanks for reading


    Georges

    Hello Legros,

    We are not aware of this issue - can you send us a sample project - this will be of great help.

    Best wishes,
