当我按下gridview内的按钮时会发生这种情况，奇怪的是我有另一个gridview，也有一个运行不同代码的列中的自定义按钮，但没有错误。下面是页面代码和代码隐藏。

}
else
{
LoggedInUser.Value = Membership.GetUser().UserName.ToString();
}
DayOfTheWeekHiddenField.Value = Convert.ToString(Request.QueryString["dow"]);
}
else
{
Response.Redirect("default.aspx");

我现在想知道，这与GridView在Ajax Tab Container内的事实有什么关系吗？因为我的另一张表工作正常不是......
注意：由于字符限制，不得不从页面中删除一些代码
答案 0 :(得分：18)
1）GridView中的无效回发或回调参数问题可能是：您正在使用对象数据源或带有函数调用的手动绑定将Page_Load事件中的数据绑定。这将使您的GridView在任何控件的每个事件触发时绑定数据。
当您使用OnRowCommand触发任何GridView命令时，在RowCommand触发之前，您的GridView将重新绑定，并且其中的所有控件都将分配给新ID。因此RowCommand无法获取已触发事件的项目。
GridView中无效回发或回调参数的解决方案：您可以在此条件下绑定数据
if (!IsPostBack)
{
//Your code for Bind data
}
如果这不起作用，此代码肯定会给你解决方案，然后检查是否有任何其他控件没有给出错误。
答案 1 :(得分：1)
您是通过javascript还是Ajax更新Grid或任何此类控件。
如果是这种情况，那么你可能会遇到这种情况。可能的解决方案是将EnableEventValidation设置为false。
答案 2 :(得分：0)
要尝试的一些事情
Page Load事件中，添加对!Page.IsPostBack的检查，并在那里移动非身份验证代码块。LinkButton代替常规按钮进行实验。答案 3 :(得分：0)
这可能是因为您正在使用的任何第三方控件。
我也有这个错误。在我的情况下，我在更新面板和内部转发器控件内有一个转发器控件我正在使用telerik datepicker控件。它在IE中运行良好，但在mozilla和chrome中没有。我通过从chrome和IE发送请求检查了两种情况下的表单数据，发现触发控制值略有不同。我使用telerik RadAjaxmanager而不是updatepanel错误消失了。
答案 4 :(得分：0)
我测试了上述所有解决方案和其他帖子，但我的问题没有解决。
在服务器端的网格事件结束时取消事件解决了我的问题。
当我们使用gridview的edit事件时，发生了此类问题。 只需添加e.Cancel = true;在活动结束时。
protected void grdEducation_RowEditing(object sender, GridViewEditEventArgs e)
{
// do your processing ...
// at end
e.Cancel = true;
}
