I think InkCanvas is a good choice if you plan on using the ink features. Otherwise, you can use just Canvas or maybe a Decorator. It also depends on how you want to manipulate items in x,y space. Do you want to use pixels or do you want to use DIUs?

Hi Will,

What I meant by that is that child elements in a Canvas are constrained and are always at the position you specify because Canvas does not have any layout so the children are absolute positioned. I should have been more clear on what I meant. I only offered up Decorator as an example if you did not want to manage multiple children. Either creating your own or using Border if you don't want to roll your own. If you need multiple children I would suggest either Canvas or creating your own Panel.

If you run into any trouble, let me know. I can whip up an example for you using a canvas.
