更改为边框为1px:

        private static void OnShowBorderChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            var grid = d as Grid;
            if((bool)e.OldValue)
            {
                grid.Loaded -= (s, arg) => { };
            }
            if((bool)e.NewValue)
            {
                grid.Loaded += (s, arg) =>
                {

                    //这种做法自动将控件移动到Border里面来
                    var controls = grid.Children;
                    var count = controls.Count;

                    for(int i = 0; i < count; i++)
                    {
                        var item = controls[i] as FrameworkElement;
                        var border_left = new Border()
                        {
