I need to determine if the issue is my version of the implementation of drag/drop or if I am missing something in code. The version we are using is 2013.3.1204.1050 (I realize it is old however very stable for us).
The issue I am having is on the grid's drag/drop behavior, the TreeViewDragDropOptions returns back as null when dragged from the TreeView to the grid. I have no idea why when the argument's data property contains the object being dragged over to the grid. Any help would be appreciative.
