註冊子控制元件的PreviewMouseWheel，然後在滾動的時候設定控制元件的 IsHitTestVisible = false，因為這個引數設為false之後子控制元件裡面的TextBox,CheckBox會失效，所以在停止滾動後要把引數設回來。程式碼如下

 private void girdOrder_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
        {
            RetryUtil.TimeOutAction(200, () =>
            {
                
 
this.Dispatcher.Invoke(() =>
                {
                    this.IsHitTestVisible = false;
                });
            },
            () =>
            {
                this.Dispatcher.Invoke(() =>
                {
                    this.IsHitTestVisible = true;
                });

            });
        }
 

下面是TimeOutAction的程式碼片

        /// <param name="OnAction">執行任務</param>
        /// <param name="TimeAction">超時處理任務</param>
        public static void TimeOutAction(int TS, Action OnAction, Action TimeAction)
        {
            CancellationTokenSource cts 
 
= new CancellationTokenSource(TS);
            cts.Token.Register(() =>
            {//等待設定時間後執行
                TimeAction();
            });
            Task.Factory.StartNew(() =>
            {//立即執行
                while (!cts.Token.IsCancellationRequested)
                {
                    OnAction();
                    Task.Delay(TS).Wait();
                }
            }, cts.Token);
        }
