如何在wpf中使用c＃拖动基于xml标签的T形处理程序？

Question

图像中的蓝色标记线是我的canvas。使用画布设置顶部，我试图使用计时器移动拇指（T形图像）。现在我正在使用计时器运行，以便基于计时器我的处理程序正在移动。但是我需要自动移动以及拖动处理程序位置。当我拖动完成后，我需要从放下处理程序的地方开始过渡。

任何人都可以帮助我实现这一目标吗？

我的xml文件

在此xml中，我的视图标签位于底部。如何通过处理程序拖动链接我的标签。例如，视图id = t_06，如果我将处理程序中的t图像拖到底部，它应该给我一些变量a = t_06的值。如果我向上移动与小鼠leftbutton它应该给一个= t_04或t_03这样。

用于t处理程序的wpf xaml代码

我获得了视图索引，并且也能够完成我的任务。下面是代码
