我在ajax更新面板中使用了一个asp.net文本框。如果我在文本框中输入&＃并按下保存按钮，则会出现javascript错误

I am using an asp.net text box inside ajax update panel. If I enter &# in the textbox and press Save Button , it gives a javascript error

Sys.WebForms.PageRequestManagerServerErrorException：未知错误在服务器上处理请求时发生。从服务器返回的状态代码是：500

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

推荐答案

当您在多个更新面板中将控件注册为AsyncPostbackTrigger时，有时会出现此问题。

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

如果这不是问题，尝试在脚本管理器声明后添加以下内容：

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>
