无效的回发或回调参数。使用'<pages enableEventValidation="true"/>'启用事件验证

当我从客户端返回一个页面时，我得到以下错误。我有JavaScript代码，修改asp:ListBox在客户端。

我们如何解决这个问题?

错误详情如下:

Server Error in '/XXX' Application.

当前回答

您可以在.aspx页面中尝试类似的操作

add

EnableEventValidation=“false”

你可以随便问任何问题!

我知道这是一个超级老的帖子。假设你正在调用你的应用程序，这里有一个对我有用的想法:

在页面上实现ICallbackEventHandler ClientScriptManager打电话。GetCallbackEventReference调用服务器端代码正如错误消息所述，您可以调用ClientScriptManager。RegisterForEventValidation

如果你不需要完全控制，你可以使用一个更新面板来为你做这件事。
