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

供参考，我有同样的错误消息的问题，这是我在同一页上有2个表单标签。一个在母版页，一个在页面本身。一旦我删除了第二个形式标签对，问题就消失了。

其他回答

此错误将在没有回发的情况下显示

添加代码:

If(!IsPostBack){

 //do something

}

这个问题的一个简单解决方案是在页面加载时使用IsPostBack检查。这样问题就解决了。

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!

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。

(1) EnableEventValidation = " false "...................这对我没用。

(2) ClientScript.RegisterForEventValidation……这对我没用。

解决方案1:

在GridView中将Button/ImageButton更改为LinkButton。它的工作原理。(但我喜欢ImageButton)

研究:Button/ImageButton和LinkButton使用不同的回发方法

解决方案2:

在OnInit()中，输入如下代码来设置Button/ImageButton的唯一ID:

protected override void OnInit(EventArgs e) {
  foreach (GridViewRow grdRw in gvEvent.Rows) {

  Button deleteButton = (Button)grdRw.Cells[2].Controls[1];

  deleteButton.ID = "btnDelete_" + grdRw.RowIndex.ToString();           
  }
}
