resize control

Question

Hi all, I am trying to create a custom control that would be resizeable. Instead of having handles like the usual control resize technique, I want to be able to resize with all the edges. I have implemented mousedown, mousemove, mouseup events on the controls. when i am testing it on the runtime window there is a lot of flickering. and also the resized control is not of desireable size. can someone help me out with a sample mouse move event to do this. any help is greatly appreciated
