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。

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。

如果你把UseSubmitBehavior="True"改成UseSubmitBehavior="False"，你的问题就解决了

<asp:Button ID="BtnDis" runat="server" CommandName="BtnDis" CommandArgument='<%#Eval("Id")%>' Text="Discription" CausesValidation="True" UseSubmitBehavior="False" />

我的问题解决时取消事件结束时网格事件在服务器端。

protected void grdEducation_RowEditing(object sender, GridViewEditEventArgs e)
{
  // do your processing ...

  // at end<br />
  e.Cancel = true;
}

最好的选择是使用隐藏字段，不禁用事件验证，也改变每个列表框，下拉列表选择与runat服务器属性

如果您使用Ajax更新面板。添加<Triggers>标签，并在其中使用<asp:PostBackTrigger…/>触发按钮或控件导致回发
