TableLayoutPanel responds very slowly to events

by

Use this code.

public class CoTableLayoutPanel : TableLayoutPanel
{
    protected override void OnCreateControl()
    {
        base.OnCreateControl();
        this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.CacheText, true);
    }

    protected override CreateParams CreateParams
    {
        get
        {
            CreateParams cp = base.CreateParams;
            cp.ExStyle |= NativeMethods.WS_EX_COMPOSITED;
            return cp;
        }
    }

    public void BeginUpdate()
    {
        NativeMethods.SendMessage(this.Handle, NativeMethods.WM_SETREDRAW, IntPtr.Zero, IntPtr.Zero);
    }

    public void EndUpdate()
    {
        NativeMethods.SendMessage(this.Handle, NativeMethods.WM_SETREDRAW, new IntPtr(1), IntPtr.Zero);
        Parent.Invalidate(true);
    }
}

public static class NativeMethods
{
    public static int WM_SETREDRAW = 0x000B; //uint WM_SETREDRAW
    public static int WS_EX_COMPOSITED = 0x02000000; 


    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam); //UInt32 Msg
}
