这看起来像回答你的问题。作为一个优先;它似乎在每个浏览器工作不只是FF。

如果您使用的是IE那么它很简单，只是把code在
页面指令。＆LT;％@页面语言=C＃AutoEventWireup =真
codeFILE =Default.aspx.cs继承=_默认
MaintainScrollPositionOnPostback =真正的％GT;
但它不会在Firefox工作了，你必须添加一个浏览器
文件到您的网站
右键单击解决方案资源管理>添加新项
选择浏览器文件，并将其添加到App_Browsers文件夹中。
添加MaintainScrollPositionOnPostback能力，这个浏览器文件
下面写的。＆LT;＆浏览器GT;
＆LT;浏览器REFID =Mozilla的＆GT;
＆LT;能力与GT;
＆LT;功能名=supportsMaintainScrollPositionOnPostbackVALUE =真/＆GT;
＆LT; /能力和GT;
＆LT; /浏览器＆GT;
＆LT; /浏览器＆GT;
有些时候，这也不能正常工作，
然后一个简单的解决方案只是网后添加一个空白更新面板
和onpostback只是把焦点放在上一个更新面板将在工作
任何浏览器。
在CS postbackevent updatepanel1.Focus（）;
如果有任何问题只是随意问或任何修改的回复。
I am a beginner at ASP.NET and I have a problem maintaining the scroll position of the page after a partial postback of an UpdatePanel. I tried setting
MaintainScrollPositionOnPostback="true"in<%@ Page Language="C#" ...%>but it didn't do the trick. Please note that I am using (and have to use) FireFox.Any help would be appreciated. Thank you! Here is my code:
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server"> <asp:HiddenField ID="ClassificationHiddenField" runat="server" /> <asp:HiddenField ID="DateHiddenField" runat="server" /> <table> <tr> <td> <asp:Panel ID="GroupTitlePanel" CssClass="titlePanelBold" BorderStyle="Ridge" runat="server" Width="400px"> <table id="MainTable"> <tr> <td align="center" class="style3"> <asp:Label ID="GroupLabel" runat="server"> </asp:Label> </td> <td align="center" class="style4"> <asp:Label ID="ReturnLabel" runat="server" Text="Expected Return"> </asp:Label> </td> </tr> </table> </asp:Panel> <br /> <asp:Panel ID="GroupMainPanel" runat="server" Width="400px"> </asp:Panel> </td> <td width='100px'> </td> <td> </td> </tr> </table> <asp:Panel ID="BottomPanel" runat="server" BorderStyle="Ridge"> <table> <tr> <td align="center"> <br /> <asp:ToolkitScriptManager ID="ToolkitScriptManager1" EnablePartialRendering="true" runat="server"> </asp:ToolkitScriptManager> <asp:CheckBoxList runat="server" ID="GroupCheckBoxList" RepeatColumns="10" RepeatDirection="Horizontal" RepeatLayout="Table" AutoPostBack="true" ClientIDMode="AutoID" OnSelectedIndexChanged="GroupCheckBoxList_SelectedIndexChanged"> </asp:CheckBoxList> </td> </tr> <tr> <td> <asp:UpdatePanel ID="GroupUpdatePanel" runat="server" Visible="true" UpdateMode="conditional"> <ContentTemplate> <asp:Panel ID="GroupGraphPanel" runat="server" Visible="true"> </asp:Panel> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="GroupCheckBoxList" EventName="SelectedIndexChanged" /> </Triggers> </asp:UpdatePanel> </td> </tr> </table> </asp:Panel>解决方案This looks like the answer to your question. As a plus; it appears to work on every browser not just FF.
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 > 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>
Some times this also not work,
Then a simple solution just add a blank Update panel after the grid and onpostback just put the focus to that update panel it will work in any browser. in cs postbackevent updatepanel1.Focus();
If any problem just feel free to ask or any modification reply.
