ASP.NET Focus将页面滚动到输入

Question

I have a few textboxes/labels inside of an UpdatePanel. When I tab out of one of the textboxes, a label has to be updated with some text. This causes focus on the page to reset to the topmost element.

This is a data-entry form and the users expect to not have to use the mouse at all. I can set focus back on the correct textbox in code:

Page.SetFocus(tbxInput);

or

tbxInput.Focus();

In IE, the browser scroll position is maintained (woo hoo!). In Chrome and Firefox it is not; the scroll location is adjusted so that the focused textbox is the last element shown on the page. This is really disturbing to the user.

I am using the following rules in my web.config:

<pages theme="Default" styleSheetTheme="Default" maintainScrollPositionOnPostBack="true" validateRequest="false">

How can I achieve the behavior that IE has?

对于这种情况，我从javascript更新了标签文本（可能使用对Web服务或页面方法的AJAX调用）。

Using asp.net AJAX UpdatePanel is an option. Also which version of .net framework are you using.

As per this with 4.0 it should work but I haven't tried.
