flicker in control

[dragonslayer008]

I have made a custom control which displays a 3D object. The user can
use the mouse to animate the object. However, I am getting bad
flicker from the control. I call Invalidate in the mouse move handler
to animate the object.
I think the problem is the control repaints itself and then I draw
over that myself, so it gets painted twice causing the flicker. In
Win32 I would use a null brush or handle the WM_ERASEBKGND message to
prevent this. Is there a flag I can set in the control to let it know
I will do all the drawing?

Following code enables double-buffering on a control :

ctrl.SetStyle(ControlStyles.DoubleBuffer |
ControlStyles.UserPaint |
ControlStyles.AllPaintingInWmPaint,
true);
ctrl.UpdateStyles();
