我有一个基本的网络论坛，人们填写并发送电子邮件。我在网站上有大约二十几个。一个人出于某种原因没有在IE中工作。它可以在Firefox，Chrome，Opera等中运行和发送......

IE error:

Server Error in '/' Application.

Invalid postback or callback argument. Event validation is enabled using in     
configuration or <%@ Page EnableEventValidation="true" %> in a page. For security   
purposes, this feature verifies that arguments to postback or callback events 
originate from the server control that originally rendered them. If the data is valid 
and expected, use the ClientScriptManager.RegisterForEventValidation method in order 
to register the postback or callback data for validation.

Description: An unhandled exception occurred during the execution of the current web   
request. Please review the stack trace for more information about the error and where 
it originated in the code.

内置不接受 html 或IIS服务器aspx页面上的代码。

这是一个安全风险，但它会让一切都飞到服务器上。

<%@ Page ValidateRequest="false"

您可能应该对客户端上的数据进行编码，以便安全地飞到服务器上。
