推荐答案

您可以尝试将其放入您的表单类：

You can try to put this into your forms class:

private const int WM_HSCROLL = 0x114;
private const int WM_VSCROLL = 0x115;

protected override void WndProc (ref Message m)
{
    if ((m.Msg == WM_HSCROLL || m.Msg == WM_VSCROLL)
        && (((int)m.WParam & 0xFFFF) == 5))
    {
        // Change SB_THUMBTRACK to SB_THUMBPOSITION
        m.WParam = (IntPtr)(((int)m.WParam & ~0xFFFF) | 4);
    }
    base.WndProc (ref m);
}

您也可以将其添加到您的表单类构造函数：

You could also add this to your forms class constructor:

SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true);

Im使用windows 8，我不会从面板得到闪烁AutoScroll =但上述方法应该可以解决闪烁。

Im using windows 8, and i dont get flicker from a panel with AutoScroll=true. but the above methods should solve the flicker.
