C# 拖放时，gui冻结

我有一个材料设计的拖放弹出框。拖放完成后，gui将冻结，并且不断更新的数据不会刷新。我怎样才能解决这个问题？在单独的线程中运行是错误的吗？是否有一点被忽略了？还是一切都错了

我的鼠标密码

private void PortableButton_MouseUp(object sender, MouseButtonEventArgs e)
    {
        ThreadPool.QueueUserWorkItem(state => {
            PortableButton.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, new Action(() =>
        {
            e.MouseDevice.Capture(null);
        }));
        });
    }

我添加了xaml代码。屏幕上不断刷新数据。我用一个带有串口的特殊协议得到这些。由于这将是一个很长的代码，可以尝试使用计时器中计数的for循环。

您可以添加您的XAML和其他相关内容，以便我可以重现您的问题吗？我添加XAML代码。屏幕上不断刷新数据。我用一个带有串口的特殊协议得到这些。因为这将是一个很长的代码，所以可以尝试使用计时器中计数的for循环。
