Windows Forms doesn't really support transparent controls.
You can work around this limitation by overriding the CreateParams property of the control and setting a custom style (look it up on google).

Finally you should override the OnPaintBackground method, as you have done, to make sure no background is painted.

Quite clumsy, and not perfect, but it should work.
