可能是什么原因呢？任何人都看过吗？

编辑：

所以，我找到了原因，这是happenning。在Page_Load中结束，我编写调用加载新领域进入一个div一个jQuery函数一个javascript线。所以，正如我所看到的，这导致在视图状态上产生不一致。禁用ViewState不适用于这种情况。它适用于FF，并且它在IE上出错。任何人？

谢谢

Answer 1

刚才碰到了这个。从您通过jquery加载的页面中删除表单标记。

Answer 2

有同样的问题，我为什么因为我发了完整形式的字符串转换成JavaScript方法，然后贴在表格得到的错误是原因。

这是一个有点沉重，我的修补程序是通过JavaScript在这个岗位只发送表单数据系列化JSON，然后创建和发布形式，等等。

Answer 3

无效的视图状态没有任何价值的记录或用户或为您的网站 避免这种错误尝试添加以下在Global.ascx：

void Application_Error(object sender, EventArgs e) 
    {   
       if (ex is HttpException && ex.InnerException is ViewStateException) 
       { 
        Response.Redirect(Request.Url.AbsoluteUri); 
        return; 
       } 
    }
