推荐答案

if you are using IE then its very simple just put the code in your page directive.

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default"

MaintainScrollPositionOnPostback="true" %>

but it will not work in Firefox for that you have to add one browser file into your website

Right click on solution explorer and Add New Item

Select Browser File and add it to App_Browsers folder.

Add MaintainScrollPositionOnPostback capability to this browser file as written below.

<browsers>
  <browser refID="Mozilla">
      <capabilities>
        <capability name="supportsMaintainScrollPositionOnPostback" value="true" />
    </capabilities>
  </browser>
</browsers>

ok, I have your solution. First use below in .aspx page
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MaintainScrollPositionOnPostback="true"%>
now after that put below code in code behind file
protected void Page_Load(object sender, EventArgs e)
{
SmartNavigation = true;
}
now create a default folder of App_Browsers in root directory and add new item, select browser.browser file and set its name like SafariFix.browser and put replace below code
<!--
You can find existing browser definitions at
<windir>\Microsoft.NET\Framework\<ver>\CONFIG\Browsers
-->
<browsers>
<browser id="NewBrowser" parentID="Mozilla">
<identification>
<userAgent match="Unique User Agent Regular Expression" />
</identification>
<capture>
<userAgent match="NewBrowser (?'version'\d+\.\d+)" />
</capture>
<capabilities>
<capability name="browser" value="My New Browser" />
<capability name="version" value="

{version} / >
< / capabilities >
< ; / browser >
< 浏览器 refID = Safari1Plus >
< 功能 >
< 功能 名称 = supportsMaintainScrollPositionOnPostback value = true / >
< / capabilities >
< / browser >
< / browsers >
它将彻底解决您的问题，因为我已经测试过了在所有三个浏览器中

{version}" /> </capabilities> </browser> <browser refID="Safari1Plus"> <capabilities> <capability name="supportsMaintainScrollPositionOnPostback" value="true" /> </capabilities> </browser> </browsers> it will completely solve your problem, because i already tested in all three browsers
