Hi Niki thanks for answer quickly. But I make a straight Window Control Library project so my control derived from class UserControl. When I use it on the Form I see that it already has Anchor and Dock properties. The above image display the control set anchor to Top Left Right Bottom. When I enlarge the form containing the custom control it also enlarge(that's what I want) overlap other control(that's what I don't expect) even when I set those button to anchor too. If I don't set anchor for the custom control it just simply go to the center of the form when I enlarge my form. The admin send me some articles about custom control and I think I should deal with the Resize event. But the one I need now is some explanation about the behavior of the control. Why the buttons don't detect that the eclock control has change it size and move according to the change just like an normal control do when setting anchor? Is there any book saying deeply about it?

Friend When you create the cusotm control do you use a panel or some other container? Define a public property to set anchor of the container in custom control. Then try to set it from the form where you use the control.
