Clear

The Clear method clears the content storage unit for this drag-and-drop object.

void Clear ();

DISCUSSION

When your part initiates a drag, you must call this method immediately before calling the GetContentStorageUnit method. Doing so ensures that the content storage unit is empty and ready for drag-and-drop data transfers.

EXCEPTIONS
