Hi
We had no issues beforehand, and everything else seems to work like a charm. But DragAndDrop throws a null reference exception from "OnDragLeave" whenever we try to drag and drop either a column (grouping in your gridview) or try to drag an appointmentitem inside your ScheduleView. It works as long as we keep the mouse inside the original item that is being dragged (supposedly because OnDragLeave never fires). Another funny thing is that if you are really, really, fast - you might be able to drop it before OnDragLeave causes the whole chain to collapse, but that is not a sustainable solution...
Got any ideas as to what might have changed since Q2 2012, any suggestions on how to proceed?
Thanks in advance!
Best regards,
Alexander
