disable background painting

I'm using visual studio 2008

I have a control that dispays a processed image. Whenever the processing parameters are changed, I'd like to update this picture, but without flickering. If I could prevent windows from blanking the area before I paint, the flicker should, for the most part go away.

Question is, how to do this?

Something like: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); Should do it, except that requires me to subclass the TableLayoutPanel control (something I spent an hour trying to do), and with what I achieved, that had no effect.

Is there an easy way to turn off background painting of my control?

Have you tried overriding the OnPaintBackground event and doing nothing?

protected override void OnPaintBackground(PaintEventArgs pevent)
{
}

try this:

this.SuspendLayout();
// do update here
this.ResumeLayout();

Clarification: this is the form
