使用ASP.NET和C#“Base-64字符串中的无效字符”

我在发布页面时遇到了这个问题.该页面有一个由下拉列表的onchange调用的jquery ajax加载,如果我禁用onchange,帖子可以工作.

“状态信息对于此页面无效,可能已损坏”

可能是什么原因？以前有人见过吗？

谢谢

编辑：

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上有缺陷.任何人？

谢谢

解决方法
