Provides information about a dragged item in relation to its data source during a drag-and-drop operation within a hierarchy window. The interface extends and inherits from the IVsHierarchyDropDataSource interface. You only need to use IVsHierarchyDropDataSource2 if you need the additional methods.
The IVsHierarchyDropDataSource2 type exposes the following members.
|OnBeforeDropNotify||Enables the drag source to prompt to save unsaved items before dropping. Notifies the source hierarchy that information dragged from it is about to be dropped on a target. This method is called immediately after the mouse button is released on a drop.|
