MaintainScrollPositionOnPostback页面指令不能与ajaxtoolkit控件一起使用?

标签: asp.net ajax asp.net-ajax postback

我在TestPage.aspx中使用UpdataPanel来解决MaintainScrollPositionOnPostback的问题 页。
页眉:

<%@ Page Language="C#" MasterPageFile="~/MasterPages/Abc.master" AutoEventWireup="true"
    MaintainScrollPositionOnPostback="true" CodeFile="Testpage.aspx.cs" Inherits="Testpage"
    Title="Test Page" %>


我将Ajaxtoolkit Control注册到我的aspx页面。 与

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxtoolkit" %>

当我将“MaintainScrollPositionOnPostback =”true“”页面指令添加到我的.aspx页面时 然后我收到了错误信息,如附图所示。

页面指​​令 - “ MaintainScrollPositionOnPostback ”无效 原因是1)Framework 2.0和
2)AjaxToolkit(ver 1.0.2 ....)

在AJAX(异步调用)回发后重置位置不支持。< / p>
