如果你试图在ASP.NET中解决这个问题（意思是：在服务器部分），你将不得不执行如此频繁的回发，它将减慢操作太多。相反，您需要在客户端完成所有操作。我建议通过JavaScript使用HTML5画布：

请参阅交互式画布图形有多么令人印象深刻： http://net.tutsplus.com/articles/web-roundups/21-ridiculously-impressive-html5-canvas-experiments [< a href =http://net.tutsplus.com/articles/web-roundups/21-ridiculously-impressive-html5-canvas-experiments\"target =_ blanktitle =New Window> ^ ] 。

If you try to solve this problem in ASP.NET (meaning: on the server part), you will have to perform so frequent postbacks, that it will slow down operation too much. Rather, you need to do it all on client side. I would advise to use HTML5 canvas, via JavaScript:

Please see how impressive the interactive canvas graphics can be: http://net.tutsplus.com/articles/web-roundups/21-ridiculously-impressive-html5-canvas-experiments[^].
