Drag and Drop (plus snapping to grid)

Is there a way in Silverlight, to make elements draggable - but also allow these same elements to "snap" to the others?

I've followed a few drag-drop tutorials for开发者_Python百科 this, but none of them seem to allow the snapping :(

Any ideas SO gurus?

Clarification: I would like a 32px x 32px "rectangle" to be draggable and snappable to other draggable elements.

This has been sorted, please see my other Silverlight Question for the answer.
