我已经把头发拉了2天没有成功。
正如您可以阅读的主题一样，当用户单击GridView中的链接时，我只是试图阻止网页滚动到页面顶部。但GridView位于ContentPlaceHolder中，该主页设置在母版页上。
我已经通过Google查看了所有可能的解决方案，甚至是在运行时构建jscript代码的新程序集ided，但都失败了。
这是我的母版页：

以上是我的GridView的上述页面之一...

AutoEventWireup="true" CodeFile="ClassAttendance.aspx.cs"
Inherits="Attendance_ClassAttendance"
Title="Class Attendance" Culture="en-AU"%>

<asp:GridView ID="gvStudents" runat="server" AutoGenerateColumns="false" AllowSorting="true" CellPadding="2" ShowFooter="true" DataKeyNames="AttendanceID"
OnRowDataBound="GridView_RowDataBound" OnDataBound="GridView_DataBound" EnableSortingAndPagingCallbacks="False">
...

</asp:GridView>
</asp:Content>

我已经尝试了几种解决方案，如上所述......
How to persist scroll position using Master Page? ASP page scrolls to top on UpdatePanel update http://www.dotnetspark.com/links/41291-how-to-prevent-master-page-postback-when.aspx http://www.4guysfromrolla.com/articles/111704-1.aspx
最后一个链接看起来最有希望，但我认为它是针对具有简单表单的非主页面网站编写的。
我还尝试了通常的解决方案来放置SmartNavigation标签......
Page.MaintainScrollPositionOnPostBack = true;
以上都没有。
我怀疑是因为我使用的是ContentPlaceHolder？也许我应该在它周围放一个<div></div>？我试过了，但也没用。
感谢您的支持。
干杯

您可以尝试在内容占位符中添加div标记，然后设置属性overflow = scroll。它可能会奏效。
<div style:"overflow=scroll">
<!--Your code-->
</div>

删除带有花哨CSS的ASP.net页面的href="#"和技巧，看起来像蓝色链接，鼠标也会改变。它有效。
