gridview中的最后一行没有到达rowCommand代码块

我有一个gridview与rowCommand设置为其中一列。一切工作正常，但我得到这个奇怪的错误，为每一行在gridview。RowCommand块不执行。除了最后一行，其他行都可以。如果我对网格视图进行排序，最后一行出现在顶部，它可以正常工作，但任何一行出现在底部，仍然不工作。

和我的服务器端代码

protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write("zarejdame stranitsata <br />");
            //BindServerTime();
            // set display preferences
            gvSchedules.PageSize = UsersHelper.GetDisplayItemsPerPage();
            if (!IsPostBack)
            {
                chkRecursive.Visible = (PanelSecurity.EffectiveUser.Role != UserRole.User);
                // toggle controls
                //btnAddItem.Enabled = PackagesHelper.CheckGroupQuotaEnabled(
                 //   PanelSecurity.PackageId, ResourceGroups.Statistics, Quotas.STATS_SITES);
                searchBox.AddCriteria("ScheduleName", GetLocalizedString("Text.ScheduleName"));
                searchBox.AddCriteria("Username", GetLocalizedString("Text.Username"));
                searchBox.AddCriteria("FullName", GetLocalizedString("Text.FullName"));
                searchBox.AddCriteria("Email", GetLocalizedString("Text.Email"));
                bool isUser = PanelSecurity.SelectedUser.Role == UserRole.User;
                gvSchedules.Columns[gvSchedules.Columns.Count - 1].Visible = !isUser;
                gvSchedules.Columns[gvSchedules.Columns.Count - 2].Visible = !isUser;
                Response.Write("page load za parvi pat<br />");
            }
            Response.Write("krai na page load<br />");
        }
protected void odsSchedules_Selected(object sender, ObjectDataSourceStatusEventArgs e)
        {
            if (e.Exception != null)
            {
                ProcessException(e.Exception);
                e.ExceptionHandled = true;
            }
        }
protected void gvSchedules_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        Response.Write("1111");
        Response.Write("aaaa " + e.CommandArgument + "<br />");
        int scheduleId = Utils.ParseInt(e.CommandArgument.ToString(), 0);
        if (e.CommandName == "start")
        {
            Response.Write("start schedule<br />");
            try
            {
                int result = ES.Services.Scheduler.StartSchedule(scheduleId);
                if (result < 0)
                {
                    ShowResultMessage(result);
                    return;
                }
            }
            catch (Exception ex)
            {
                ShowErrorMessage("SCHEDULE_START_TASK", ex);
                return;
            }
        }
        else if (e.CommandName == "stop")
        {
            try
            {
                int result = ES.Services.Scheduler.StopSchedule(scheduleId);
                if (result < 0)
                {
                    ShowResultMessage(result);
                    return;
                }
            }
            catch (Exception ex)
            {
                ShowErrorMessage("SCHEDULE_STOP_TASK", ex);
                return;
            }
        }
        // rebind grid
        gvSchedules.DataBind();
    }

我没有任何东西在我的PageLoad。通过调试，我可以看到输入触发了最后一行的回发，它到达了页面加载，但从未到达rowCommand代码块。Response.Write("1111");从不露面。有什么想法都会有帮助的。
