Sys系统。 WebForms的。 PageRequestManagerServerErrorException状态代码：500

一切正常，除非CheckBoxList有很多元素（数千个项目），然后我点击并检查了另一个div的复选框，然后发生以下错误：

Everything works fine, except when the CheckBoxList has many elements (thousands of items) and I click on the and i checked the other div's checkbox then the following error occurs:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

此错误发生在ScriptResource.axd之一

This error occurs in one of the ScriptResource.axd

推荐答案

Quote：

当您将控件注册为AsyncPostbackTrigger时，有时会出现此问题多个更新面板。

This issue sometimes occurs when you have a control registered as an AsyncPostbackTrigger in multiple update panels.

如果这不是问题，请在脚本管理器声明后尝试添加以下内容：

If that's not the problem, try adding the following right after the script manager declaration:

<script type="text/javascript" language="javascript">
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
    function EndRequestHandler(sender, args){
        if (args.get_error() != undefined){
            args.set_errorHandled(true);
        }
    }
</script>
