问题陈述 触发事件时，updateprogress 会无限期运行，更新面板不会刷新，或者请求不会在 IIS 8.5 (Windows Server 2012) 中结束。

以下代码供参考

已经尝试过的事情

  1. 在 web.config 中添加处理程序

网页配置

    <!--<add assembly="Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
    <add assembly="Microsoft.ReportViewer.Common, Version=9.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>-->
  </assemblies>
</compilation>
<!--
        The <authentication> section enables configuration 
        of the security authentication mode used by 
        ASP.NET to identify an incoming user. 
        <authentication mode="Windows"/>
    -->
<!--<authentication mode="Windows" />-->
<authentication mode="Forms">
  <forms loginUrl="logon.ashx" name="AuthCookie" timeout="60" path="/"></forms>
</authentication>
<authorization>
  <deny users="?" />
  <allow users="*" />
</authorization>

<trust level="Full" originUrl="" />


<!--
        The <customErrors> section enables configuration 
        of what to do if/when an unhandled error occurs 
        during the execution of a request. Specifically, 
        it enables developers to configure html error pages 
        to be displayed in place of a error stack trace.

    <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
        <error statusCode="403" redirect="NoAccess.htm" />
        <error statusCode="404" redirect="FileNotFound.htm" />
    </customErrors>

    -->
<customErrors mode="Off" defaultRedirect="ErrorPageInternal.aspx" />

.Net 框架是 4.5.2

在危机中，在周五之前使之可行。任何帮助/线索将不胜感激。

提前致谢。
