How to cancle drag and drop

Dear all,
if an object draged on the certain place on the control I would like to
cancel drag and drop. But from MSDN:
"The QueryContinueDrag event is raised when there is a change in the
keyboard or mouse button state during a drag-and-drop operation"
But if there is no such operation can I somehow cancel drag&drop?
I tried to raise this event but complier complains, that I can't raise event
in the base class.
Is there any solution?
Thanks,
Boni

You can look in the DragDrop event of the object, check the mouse
location, object.MousePosition, then if it doesn't meet your criteria
set e.Effect = Windows.Forms.DragDropEffects.None, which will not allow
the drop to occur.

But I want to cancel Drag and Drop action. Not just prohibit a drop on
special place. Is it possible?
