当我检查元素时，我在调试器中得到这些错误。 UpdatePanels根本不起作用。我正在使用AjaxToolkit。使用IIS 7.5
非常感谢任何和所有帮助。

我会检查您的防火墙日志，看看客户端是否被阻止。
我遇到此错误的唯一一次是我的防火墙阻止了回发，因为它超出了parameter length limit。
您可能会发现，如果您取消了更新面板和所有Ajax功能，那么您将无法找到＆＃34; Page＆＃34;来自防火墙的消息，但Ajax功能＆＃34;隐藏＆＃34;来自用户的错误，因此只显示在调试器中。
我的解决方案是提高__EVENTVALIDATION参数的参数长度限制（在我的情况下为1600）。现在，它可能是一个不同的限制或参数，需要在您的情况下进行更改，但如果您发现防火墙阻止了它，它应该告诉您原因。
＆＃34;如果一切都失败了，请检查您的防火墙。＆＃34;
我知道它有点迟到了，但也许这会让其他人节省我必须经历的调试和研究的一周。
我希望它有所帮助！
