Information about the drag and drop operation.

Implements
IDropHandler.IsDropEnabled(DragDropInfo)
Remarks
This method is used by the editor to check whether the drop handler can accept data after it has been designated to handle a drag and drop operation. For example, the drop handler may be able to handle data only if the view is not read-only. The implementation of this method should check the read-only status of the view. If one drop handler returns false, another drop handler may be used to handle the drop operation, even if the ordering of IDropHandler objects dictates otherwise.
