Question

我有使用ItemTemplate和EditItemTemplate的Gridview：

但是当我点击＆＃34; Ok＆＃34;按钮，没有任何反应。我试图在RowUpdating事件上添加跟踪点，然后单击＆＃34;确定＆＃34;按钮，但它甚至没有触发。我认为，这个问题可能在同一个问题上，而且＃34; Id＆＃34; ItemTemplate和EditItemTemplate lbl_first_fl。但早些时候这个工作正常，唯一的改变 - 我将Visual Studio更新到2015并将Windows更改为8.所以我安装了VS 2013，但问题仍然存在。有什么建议？或者也许我如何使用不同的id来处理它？</ p>

aspx页面：

OnRowUpdating事件：

 protected void GridView5_RowUpdating(object sender, System.Web.UI.WebControls.GridViewUpdateEventArgs e)
    {


        DropDownList First_fl = GridView5.Rows[e.RowIndex].FindControl("ddl_first_fl") as DropDownList;



        con = new SqlConnection(cs);
        con.Open();
        //updating the record  
        SqlCommand cmd_fl = new SqlCommand("Update [Duty].[dbo].[Schedule_FirstLine] set First='" + First_fl.Text + "', con);
        cmd_fl.ExecuteNonQuery();

        con.Close();

        GridView5.EditIndex = -1;

        ShowDataFirstLine();

    }

绑定网格视图：

 protected void ShowDataFirstLine()
    {
        DateTime date = Convert.ToDateTime(Calendar1.VisibleDate.Date.ToString());

        var firstDayOfMonth = new DateTime(date.Year, date.Month, 1);
        var lastDayOfMonth = firstDayOfMonth.AddMonths(1).AddDays(-1);

        string GridDS_FirstLine = "set dateformat dmy  Select DutyDate,WeekDay,First, Second from [Duty].[dbo].[Schedule_FirstLine] WHERE DutyDate >= '" + firstDayOfMonth + "' AND DutyDate <= '" + lastDayOfMonth + "'";

        dt_FirstLine = new DataTable();
        con_FirstLine = new SqlConnection(cs);
        con_FirstLine.Open();
        adapt_FirstLine = new SqlDataAdapter(GridDS_FirstLine, con_FirstLine);
        adapt_FirstLine.Fill(dt_FirstLine);
        if (dt_FirstLine.Rows.Count > 0)
        {
            GridView5.DataSource = dt_FirstLine;
            GridView5.DataBind();
        }

        GridView5.Columns[0].Visible = true;
    }

您可以像这样在网格上命名事件吗？

<asp:GridView ID="TaskGridView" runat="server" 
        AutoGenerateEditButton="True" 
        AllowPaging="true"
        OnRowEditing="TaskGridView_RowEditing"         
        OnRowCancelingEdit="TaskGridView_RowCancelingEdit" 
        OnRowUpdating="TaskGridView_RowUpdating"
        OnPageIndexChanging="TaskGridView_PageIndexChanging">
      </asp:GridView>

GridView_RowUpdating未触发
