UIElement collection bound to itemscontrol, displayed in canvas

Hey, I have an ItemsControl with a collection rectangle UI elements bound to it. These are displayed in the ItemsPanelTemplate, in a canvas. I was wondering if it would be possible to display the rectangles in this collection at different points on the canvas.

BTW, I have the ability to add rectangles at runtime and want to have them show up in the canvas, but not on top of each other.

Eventually, I want to be able to resize and drag these rectangles around the canvas.

Thanks!

I solved this problem by adding a "Position" property of type Point to the ViewModel class that these UI elements were exposing. I then wrote a style for my ItemsControl ItemContainerStyle that bound the Canvas's Left/Top properties to the ones in the ViewModel, following instructions from this site: http://drwpf.com/blog/2008/03/25/itemscontrol-i-is-for-item-container/comment-page-1/#comment-2971[^]

Haven't quite figured out how to update the ViewModel's position when I drag these elements around the canvas.
