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:

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;
}

当我在ItemDataBound上添加id时，它没有给我错误，但它没有给我命令名。它返回命令名为空。然后我添加了命令名以及ItemDataBound。然后它解决了同样的问题。谢谢Nilesh，好建议。它起作用了:)

我也遇到过同样的问题

刚刚添加了一个条件if(!IsPostBack)，它工作得很好:)

我用过DataGrid。其中一列是“选择”按钮。当我点击任何一行的“选择”按钮时，我收到了这个错误消息:

无效的回发或回调参数。事件验证使用配置或 <%@ Page EnableEventValidation="true" %>出于安全考虑，此特性验证回发或回发的参数回调事件源自最初呈现它们的服务器控件。如果数据是有效的和预期的，则使用 ClientScriptManager。RegisterForEventValidation方法，以便注册回发或回调数据进行验证。

我改了几个密码，最后成功了。我的体验路线:

1)我把页面属性改为EnableEventValidation="false"。但这并没有起作用。(这不仅危险出于安全原因，我的事件处理程序没有被调用:void Grid_SelectedIndexChanged(对象发送者，EventArgs e)

2)实现ClientScript。渲染方法中的RegisterForEventValidation。但这并没有起作用。

protected override void Render(HtmlTextWriter writer)
{
    foreach (DataGridItem item in this.Grid.Items)
    {
        Page.ClientScript.RegisterForEventValidation(item.UniqueID);
        foreach (TableCell cell in (item as TableRow).Cells)
        {
            Page.ClientScript.RegisterForEventValidation(cell.UniqueID);
            foreach (System.Web.UI.Control control in cell.Controls)
            {
                if (control is Button)
                    Page.ClientScript.RegisterForEventValidation(control.UniqueID);
            }
        }
    }
}

3)我改变了我的按钮类型在网格列从PushButton到LinkButton。它工作!(" ButtonType = " LinkButton”)。我认为如果你可以改变你的按钮到其他控件，如“LinkButton”在其他情况下，它会正常工作。

我用的是数据列表，我的按钮也出现了同样的错误。我只是使用IsPostBack检查和填充我的控件，问题就解决了!太棒了! !

我有同样的问题与Repeater，因为我有一个网页与一个网站的Repeater控件，已启用EnableEventValidation开关。这并不好。我得到无效的回发相关异常。

对我来说有用的是为Repeater设置EnableViewState="false"。它的优点是使用起来更简单，就像关闭网站或网页的事件验证一样简单，但是范围比关闭事件验证要小得多。

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