我得到一個按鈕下面的錯誤點擊與GridView控件錯誤：無效的回發或回調參數

當我按gridview的內部按鈕，奇怪的是，我有另外一個GridView控件它發生，也可以在運行不同代碼的列中使用自定義按鈕，但不會出現錯誤。以下是該頁面和代碼隱藏的代碼。
namespace CCCC
{
public partial class drivermangement : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
if (System.Web.HttpContext.Current.User.Identity.IsAuthenticated)
{
if (Roles.IsUserInRole("Administrator"))
{
LoggedInUser.Value = Convert.ToString(Request.QueryString["driver"]);
}
else
{
LoggedInUser.Value = Membership.GetUser().UserName.ToString();
}
DayOfTheWeekHiddenField.Value = Convert.ToString(Request.QueryString["dow"]);
}
else
{
Response.Redirect("default.aspx");

cmd.CommandType = CommandType.Text;
cmd.CommandText = "UPDATE Customers SET [email protected] WHERE [email protected]";
cmd.Parameters.AddWithValue("@CustomerBinNeedAcknowledged", CustomerBinNeedAcknowledged);
cmd.Parameters.AddWithValue("@CustomerId", CustomerID);
con.Open();
cmd.ExecuteNonQuery();
con.Close();

現在我想知道，這是否有什麼關係的事實，GridView是Ajax Tab Container裏面？因爲我的工作正常是不是其他表...
注：不得不削減從由於頁一些代碼字符數限制
忘記了，我不想禁用事件驗證。它只解決問題（收益，但視圖沒有更新），並使我容易受到攻擊，因爲它是一種安全措施。 – cb1295

您使用的是更新面板嗎？你是否將數據動態添加到網格中？ – NoviceProgrammer
