Bad Panel Refresh when scroll goes down

Question

Hi,
I have defined a panel and I have put many user controls on it. These controls can not be accommodated at one page and panel gets a scrollbar. When user does not move the scroll every thing is OK. The problem is when he/she is moving the scroll and panel is redrawing whatever in its page. It redraws all user controls inappropriate which looks annoying for user. Although it happens just during moving scroll, it causes the user lose where he/she is.
Is there a way to have a better refreshing?

Any idea?

thx

I'm not entirely sure if this works for controls but it sure does for drawing. You could give it a try

:(( Unfortunately, It didn't work!

You could try to make the Panel double buffered.

Create a class as following:

C#

public class PanelDoubleBuffered : System.Windows.Forms.Panel
{
    public PanelDoubleBuffered()
    {
        this.DoubleBuffered = true;
        this.UpdateStyles();
    }
}

Then instead of using the Panel use the PanelDoubleBuffered. This avoids flickering and should also fix scrolling.

I'm not entirely sure if this works for controls but it sure does for drawing. You could give it a try :)
