>Hi everybody,

>I have a mover class. It is a container with label at the top, two listboxes and 4 command buttons. I want to make listboxes change size when I change size of my cntMover. I want buttons to change position to always be in the middle of the container (the buttons are individual buttons, not the command group).

>I'm not sure if I can achieve what I want using anchor property or I should program resize event.

Yes, you can get what you want with Anchor. Set the left-hand listboxes to 135. Set the right-hand listbox to 45. Set the buttons to 768.

>Also is it possible to achive this effect in design time as well as in run-time?

No anchoring is a run-time feature.
