GridViewComboBoxColumn Animation error

[Maulik Patel]

Hi,


We are using "GridViewComboBoxColumn" in RadGridView. It has "ItemsSource" assigned and it opens the drop down while running. Now, the problem is when it is opened, if the "GridViewSelectColumn" is checked/clicked, an error is thrown (as mentioned below).


If we close the control that holds RadGridView while drop down is opened, the same error is noticed. Is there any fix for it? Am I missing something? I apologize for not providng working project right now.

at Telerik.Windows.Controls.PopupPlacement.GetPopupPlacement(DependencyObject obj)
at Telerik.Windows.Controls.AutoClosePopupWrapper.<set_IsOpen>b__0()
at Telerik.Windows.Controls.Animation.AnimationManager.InvkokeCallbacks(Storyboard storyboard)
at Telerik.Windows.Controls.Animation.AnimationManager.OnStoryboardCompleted(Object sender, EventArgs e)
at MS.Internal.CoreInvokeHandler.InvokeEventHandler(UInt32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)

Your suggestion will surely be appreciated.

Hi Maulik,

 I have created a test project based on your description.

So far I was not able to reproduce the problem. Would it be possible for you to review the attached solution and let me know what I should do in order to reproduce the issue?
