我尝试了什么：



我确实尝试更改updatemode和.Net ver。

设置

 MaintainScrollPositionOnPostback =true

但是在updatepanel刷新之后页面会上升

我还能做什么???

解决方案

试试这个

smartNavigation =trueMaintainScrollPositionOnPostback =true

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MaintainScrollPositionOnPostback="true" %>
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" ClientIDMode="AutoID">
<asp:ListItem Selected="True" Value="XXX">XXX</asp:ListItem>
<asp:ListItem Value="YYY">YYY</asp:ListItem>
</asp:DropDownList

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" CssClass="BoxShadow table table-hover table-condensed table-bordered RTL" Font-Size="Medium" Font-Bold="true" BackColor="White" BorderStyle="Double">
</asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="DropDownList1" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>

What I have tried:

I did try to change updatemode and .Net ver.
set the

MaintainScrollPositionOnPostback="true"

but the page goes up after updatepanel refresh
what else can i do???

解决方案

Try this
smartNavigation="true" MaintainScrollPositionOnPostback="true"
