When I dock a control, the resize event is not firing, but the control is obviously resized when it is docked. Since there is no event for ControlDocked, what is the solution?

Specifically, I am creating userControls, and in the designer, the contents only resize themselves when the control is resized, but when I dock the control, nothing happens. I have not tried it in runtime yet, but it does not work in the designer.

Thanks.
