UpdatePanel导致整页回发

标签： asp.net updatepanel

我遇到了UpdatePanel的问题，它总是导致整页回发而不是异步回发。

这是aspx代码

    <%@ Page language="c#" Codebehind="RegistrationsOld.aspx.cs" AutoEventWireup="True" Inherits="Registrations.Register" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Registrations</title>
    </head>
    <body>
        <form id="_mainForm" runat="server">
            <asp:ScriptManager ID="_scriptManager" runat="server"></asp:ScriptManager>
            <asp:UpdatePanel ID="_updatePanel" runat="server">
                <ContentTemplate>
                    <asp:Button ID="_postBack" runat="server" Text="Postback!!!" />
                    <%=DateTime.Now%>
                </ContentTemplate>
            </asp:UpdatePanel>
        </form>
    </body>
</html>

逻辑背后没有代码

在生成的HTML中，我注意到缺少注册UpdatePanels的所有javascript逻辑，可能出现什么问题？

                    8/6/2009 5:23:40 PM

</div>


<script type="text/javascript">

</script>
</form>
    </body>
</html>

我发现问题是问题!!!

所以，心理记录：不允许使用xhtmlComformance：D

可以找到更多信息here。

<强>摘录：

  

除非您知道您的网站在XHTML模式下运行时遇到的已知问题（以及您还没有时间修复），我总是建议您从web.config文件中删除该部分（或者您可以明确地将其设置为“Transitional”或“Strict”）。

     

这将使您的HTML输出标准符合要求。除此之外，这将导致服务器控件中的HTML“格式良好” - 意味着打开和关闭标记元素始终匹配。当您使用AJAX技术动态替换页面上某些HTML元素的内容时，这一点尤为重要（否则客户端JavaScript有时会对容器元素产生混淆并导致错误）。它还将确保ASP.NET AJAX与您的站点一起正常工作。

答案 1 :(得分：0)

您可能需要将“EnablePartialRendering = true”添加到脚本管理器

答案 2 :(得分：-2)

我的第一个想法是从所有ID名称中删除下划线。
