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.

3:我改变了我的按钮类型在网格列从“PushButton”到 “LinkButton”。它工作! ("ButtonType="LinkButton")我认为如果你可以把你的按钮换成其他的其他控件如“LinkButton” 在这种情况下，它会正常工作。

我希望我能给你投票，阿米尔(唉，我的代表太低了。)我只是有这个问题，改变这个工作就像一个冠军在我的网格视图。稍微提一下，我认为有效的代码是:ButtonType="Link"

我怀疑这是因为当你点击“编辑”时，你的编辑变成了“更新”和“取消”，然后在提交时又变成了“编辑”。这些变化的控件让。net很不舒服。

在远程服务器(生产、测试、qa、登台等)上遇到这个问题后，而不是在本地开发工作站上，我发现应用程序池配置的RequestLimit不是0。

这导致应用程序池放弃并回复问题中指出的异常。

在本例中，将id添加到网格的RowDataBound中的按钮。它会解决你的问题。

Ajax UpdatePanel可以做到这一点，我认为这是最简单的方法，忽略Ajax回发开销。
