I am programming a Form Control which acts just like the Form of VB. I want the Form Control I programmed has the resize function. Currently, I can only resize the control to the East and South. I found that the UserControl only has Width and Height property, I think this is reasonable because that in the control itself, the Left and Top should be 0. The problem is that I want to get the control's Top and Left value in its container, how can I do that?
