使用多个Updatepanel

我无法维护具有异步部分渲染的页面的滚动位置。

以下是我的aspx页面示例:

<%@ Page Language="C#" MasterPageFile="~/Main.master" AutoEventWireup="true" CodeFile="Page.aspx.cs" Inherits="Page_Page" MaintainScrollPositionOnPostback="true"%>




<asp:Content ID="ContentCo" ContentPlaceHolderID="Cph" runat="Server">



  <asp:UpdatePanel ID="UpdatePanel1" runat="server"  UpdateMode="Conditional" ChildrenAsTriggers="false"> 
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick"/>
            </Triggers>
            <ContentTemplate> 

            </ContentTemplate>
        </asp:UpdatePanel>
      <asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Interval="1"></asp:Timer>

        <asp:UpdatePanel ID="UpdatePanel2" runat="server"  UpdateMode="Conditional" ChildrenAsTriggers="false">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer2" EventName="Tick"/>
            </Triggers>
            <ContentTemplate>

            </ContentTemplate>
        </asp:UpdatePanel>
     <asp:Timer ID="Timer2" runat="server" OnTick="Timer2_Tick"  Interval="1"></asp:Timer>



   <asp:UpdatePanel ID="UpdatePanel3" runat="server"  UpdateMode="Conditional" ChildrenAsTriggers="false">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer3" EventName="Tick"/>
            </Triggers>
            <ContentTemplate>

            </ContentTemplate>
        </asp:UpdatePanel>
    <asp:Timer ID="Timer3" runat="server" OnTick="Timer3_Tick" Interval="1"></asp:Timer>


     <asp:UpdatePanel ID="UpdatePanel4" runat="server"  UpdateMode="Conditional" ChildrenAsTriggers="false">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer4" EventName="Tick"/>
            </Triggers>
            <ContentTemplate>

            </ContentTemplate>
        </asp:UpdatePanel>
    <asp:Timer ID="Timer4" runat="server" OnTick="Timer4_Tick" Interval="1"></asp:Timer>



    <asp:UpdatePanel ID="UpdatePanel5" runat="server"  UpdateMode="Conditional" ChildrenAsTriggers="false">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer5" EventName="Tick"/>
            </Triggers>
            <ContentTemplate>

            </ContentTemplate>
        </asp:UpdatePanel>
    <asp:Timer ID="Timer5" runat="server" OnTick="Timer5_Tick" Interval="1"></asp:Timer>


     <asp:UpdatePanel ID="UpdatePanel6" runat="server"  UpdateMode="Conditional" ChildrenAsTriggers="false">
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer6" EventName="Tick"/>
            </Triggers>
            <ContentTemplate>

            </ContentTemplate>
        </asp:UpdatePanel>
    <asp:Timer ID="Timer6" runat="server" OnTick="Timer6_Tick" Interval="1"></asp:Timer>


    </asp:Content>

我为每个UpdatePanel添加了aspx.cs中的所有控件,如:

var us = LoadControl("~/Controls/Control1.ascx");
 this.Controls.Add(us1);

异步部分渲染有效,但每次控件渲染它都会在页面顶部进行, 我该如何解决这个问题?

我认为我有同样的问题,并通过覆盖javascript scrollTo函数解决。我在页面中插入了以下内容

<script type="text/javascript">
    window.scrollTo = function () { }
</script>
