Hi .

I'm using TreeViewAdv control in RibbonWindow with DockingManager. 

The theme is Metro. (It is default theme for new syncfusion wpf project)

When I drag an item and drop it to empty space below tree, application throws an exception.

Please refer to the attached project and video. 

Thanks for reading.
