返回与其他基于Web的问题。

Back with another web based issue.

当控件发出回发到服务器页面刷新（精细）。该页面还向后滚动到顶部，失去所选择的控制。如果它回传取决于什么变化发生后，控制在相应和可见或隐藏制成。重点是丢失，即使什么也不页面知名度改变明智当前滚动复位。在文本字段中输入的数据被保存，因此任何单选按钮/复选框的选择。问题跳格复位为索引0和页滚动发送回页面的顶部。

When a control issues a postback to the server the page refreshes (Fine). The page also scrolls back to the top and loses the control that is selected. If it's relevent after the postback depending on what changes have happened controls are made visible or made hidden. The focus is lost and current scroll resets even if nothing is changed on the page visibility wise. The data inputted in Text fields is kept and so are any radiobutton/checkbox selections. The problem is tabbing is reset to index 0 and the pages scroll is sent back to the top of the page.

我使用.NET 4.0

我曾尝试加入MaintainScrollPositionOnPostback =真无论是ASP页面本身上，并在web.config无济于事。
我曾尝试使用和不使用条件更新引发了阿贾克斯的UpdatePanel时，文本框的文本被更改或单选按钮改变和回传还是引起了滚动和索引损失。

I have tried adding MaintainScrollPositionOnPostback="true" both on the asp page itself and in the web.config to no avail. I have tried with and without the Ajax updatepanel using conditional updating triggering off when textboxes text is changed or radiobuttons are changed and the postback still causes a scroll and index loss.

任何IDE的将是太棒了。 TA！

Any ides would be fantastic. Ta!
