Remarks

To make an UIElement droppable, you can choose one of the following approaches:

Attach a DropTargetBehavior
Set the Intersoft:ISDragDrop.AllowDrop attached property to True
Set the AllowDrop property to True

AllowDrop property is only available in SL4 and WPF.

The AllowDropItem property determines whether the attached element is dropable.
