使用ASP.NET和C＃“Base-64字符串中的无效字符”

I'm having this problem on posting a page. The page have a jquery ajax load called by the onchange of a dropdownlist, if I disable the onchange, the post works.

我在发布页面时遇到此问题。该页面有一个jquery ajax加载,由下拉列表的onchange调用,如果我禁用onchange,帖子工作。

what could be the reason for that? Anyone seen it before?

可能是什么原因?以前有人见过吗?

Thank you

EDIT:

So, I've found out why this is happenning. At the end of Page_Load, I write a javascript line that calls a jquery function that loads new fields into a div. So, as I see, this is causing to create a inconsistence on the viewstate. Disabling ViewState is not a option for this case. It works on FF, and it bugs on IE. Anyone?

所以,我发现了为什么会这样。在Page_Load的末尾,我编写了一个调用jquery函数的javascript行,该函数将新字段加载到div中。所以,正如我所看到的,这导致在viewstate上产生不一致。对于这种情况,禁用ViewState不是一个选项。它适用于FF,它在IE上有问题。任何人?

Thank you

Just ran into this. Remove the form tag from the page you are loading via jquery.

刚碰到这个。从您通过jquery加载的页面中删除表单标记。

#2

Had the same problem, the reason why I got the error was because I sent a complete form as string into a javascript method, which then posted the form.

有同样的问题,我得到错误的原因是因为我将一个完整的表单作为字符串发送到javascript方法,然后发布表单。

That was a bit heavy, and my fix was to send only the form data as serialized json, and then create and post the form through javascript, like in this post.

这有点沉重,我的解决方法是只将表单数据作为序列化的json发送,然后通过javascript创建和发布表单,就像在这篇文章中一样。

invalid view state don't have any value for your logger or for users or for your website to avoid this error try to add the following In Global.ascx:

无效的视图状态对您的记录器或用户或您的网站没有任何值以避免此错误尝试在Global.ascx中添加以下内容:

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