“Drag Shadow” while dragging item from ListBoxDragDropTarget

Question

Prevent or modify "Drag Shadow" while dragging item from ListBoxDragDropTarget in Silverlight 5

I am using ListBoxDragDropTarget for drag and drop custom user controls in Silverlight 5

Drag and drop functionality is working fine, but I have arranged control over each other with some margin so I can see bit part of each control.

The issue is while dragging one element to another ListBox, it shows shadow copy, but due to that given margin it shows only half shadow image.

So, is it possible that I can hide that shadow image or modify and it would be nice if I can create real image rather than shadow copy while element is dragging.

Thanks
