Function DoubleBufferedx(ByVal dgv As DataGridView, ByVal setting As Boolean)
        Dim dgvType As Type = dgv.GetType()
        Dim pi As System.Reflection.PropertyInfo = dgvType.GetProperty("DoubleBuffered", System.Reflection.BindingFlags.Instance Or System.Reflection.BindingFlags.NonPublic)
        pi.SetValue(dgv, setting, Nothing)
        Return True
    End Function

從前，總是使用雙重緩衝，但是這方法不管用，閃爍還是嚴重！自從stackoverflow找到一個很棒的方法後！非常有效！僅此作為筆記。

protected override CreateParams CreateParams {
  get {
    CreateParams cp = base.CreateParams;
    cp.ExStyle |= 0x02000000;  // Turn on WS_EX_COMPOSITED
    return cp;
  }
}

Protected Overrides ReadOnly Property CreateParams() As CreateParams
    Get
        Dim params As CreateParams = MyBase.CreateParams
        params.ExStyle = params.ExStyle Or &H2000000
        Return params
    End Get
End Property
