How to double buffer .NET controls on a form?

Question

How can I set the protected DoubleBuffered property of the controls on a form that are suffering from flicker?

Answer 1

Extension method to turn double buffering on or off for controls

public static class ControlExtentions
{
    /// 

    /// Turn on or off control double buffering (Dirty hack!)
    /// 
    /// Control to operate
    /// true to turn on double buffering
    public static void MakeDoubleBuffered(this Control control, bool setting)
    {
        Type controlType = control.GetType();
        PropertyInfo pi = controlType.GetProperty("DoubleBuffered", BindingFlags.Instance | BindingFlags.NonPublic);
        pi.SetValue(control, setting, null);
    }
}

Usage (for example how to make DataGridView DoubleBuffered):

DataGridView _grid = new DataGridView();
//  ...
_grid.MakeDoubleBuffered(true);
