        {
            RefreshPart part = new RefreshPart();
            container.Children.Add(part);
            part.MouseLeftButtonUp += (s, e) =>
            {
                container.Children.Remove(part);
                if (refreshCallback != null)
                    refreshCallback.Invoke();
            };
        }
    }
}

使用：RefreshPart.LoadRefreshPart(Grid_Root, action); 其中Grid_Root为要刷新的容器，action为执行的方法。。。
