Best practice for panning/zooming a user control?

We currentl开发者_如何学Pythony have a user control which displays a dynamic matrix of other user controls. Since it's dynamic, the view can become large, requiring the user to scroll up/down & left/right in the browser to view everything.

I would like to give the users one view of the user control with the ability to pan & zoom on it, much like the feel of this Telerik control. We own the Telerik controls and I've tried to use the Map control for our purpose, but it doesn't seem like that is going to be a good solution.

I have also placed a Canvas inside of a scroll viewer, and was able to make it pan (using scroll bars) & zoom (using Scale Tranform). This works pretty well, but it's not smooth like the Telerik control is.

So, I'm wondering what other ways there are to do this. Am I overlooking a Silverlight control that would work for me? Any input would be greatly appreciated!

I found this on CodePlex and I like their approach. I will probably be customizing it to be exactly what I want, but it's a good start. Note: It does not implement the 'throwing' capabilities.
