Hello,
I recently upgraded our distribution to Q2 2011 and everything works great except for dragging and dropping. I currently have a scenario where I am dragging from a ListBox to a RadChart and it still "works" but doesn't show the drag que arrow anymore. I added the following line to our code:
This error occurs while dropping onto the RadChart. We have been using this code since mid-2010 and has survived at least 3 upgrades so the problem (since it seems Telerik has extensively changed the RadDragAndDropManager and divided it into 2 parts) may lay in the fact that we need to upgrade the drag and drop code. The problem is I have no idea what to change since the documentation seems to be almost verbatim what the last documentation set had. Any help in resolving this would definitely be appreciated.
Edit: I was just testing this and I remembered that I should say that the ListBox is in a RadDock and when the tab is pinned it works fine and doesn't give the visuals error. If it is unpinned it crashes. Once again, it worked fine before the Q2 upgrade.
Thanks,
Sean Galland

RadDragAndDropManager.ExecutionMode = DragExecutionMode.Legacy;
This had no discernable effect. Also we now get an intermitten crash:
