我希望我已经在这一个做了功课。我有一个相当大的Web应用程序，当一个按钮是pressed网页跳转到上回发的页面的顶部。据我所知，页面需要行 MaintainScrollPositionOnPostback =真正的
于是我又回到了第一的原则，并建立了两个网页。其中有一个AJAX控件的无线工具包TabContainer的第二个也没有。
在一个与TabContainer的的maintainposition属性有没有影响和页面跳转回TabContainer的。在一个没有AJAX的正常工作。这两个网页下面。
能否请你告诉我，我为什么和如何解决这个问题？

解决方案
这篇文章应该解释一下：
http://www.eggheadcafe.com/tutorials/asp-net/7dd57635-0587-42ba-ae73-f52449e653bf/aspnet-ajax-maintain-scroll-position-from-a-partial-page-update.aspx
I hope I have done my homework on this one. I have a fairly large web application and when a button is pressed the webpage jumps to the top of the page on postback. I am aware that the page needs the line MaintainScrollPositionOnPostback="true"
So I went back to first principles and built two web pages. One has an ajax control tookit tabcontainer the second one has not.
On the one with the tabcontainer the maintainposition attribute has no affect and the page jumps back to the tabcontainer. On the one without ajax it works fine. Both pages are below.
Can you please tell me why and how I fix this issue?
