resize / drag usercontrol at runtime

How can I resize / drag a userco开发者_开发技巧ntrol in silverlight 4 at runtime through a resizehandle in the bottomright corner for example? As a beginner I have no idea how I can do this.

I've found exactly what I was looking for. I was using a childwindow but it blocked interaction with parent so I thought I had to create a usercontrol and built in resize function and drag function and stuff.

This guy took the childwindow and refactored it for non-modal use:
