WPF drag & drop between containers

Question

I've got a container, say a Grid. It has two containers, say StackPanels.

StackPanel #1 has some rectangles. What's the best way to enable a user to drag a rectangle and drop it in the StackPanel #2 (and have that rectangle be a child of StackPanel #2).

I've got the drag bit sussed - the only thing that's unclear is whether to actually use containers or just handle all the rectangles manually in a straight canvas.

Answer 1

As far as the logic behind actually moving the items goes, a StackPanel as a container is just fine. If you want to preview the item whilst it's being dragged, you can implement an Adorner that displays the Visual whilst it is being dragged.
