Question

private void Page_Load(object sender, System.EventArgs e)
        {            if (Session["jb"].ToString() == "0")
            {
            }
            else
            {
                Response.Write("您不是合法用户，请登入后再操作！");
                Response.Redirect("Error.aspx");
                Page.Response.End();
            } 
            
            DateTime dt = DateTime.Now;
            end.Text = dt.ToString();
            if (!IsPostBack) BindGrid();
        }        private void BindGrid()
        {
            String strConnection = ConfigurationSettings.AppSettings["ConnectionString"];            SqlConnection myConnection = new SqlConnection(strConnection);
            SqlDataAdapter da = new SqlDataAdapter("select * from classdata11 order by ID desc", myConnection);
            DataSet ds = new DataSet();
            da.Fill(ds);
            DataGrid1.DataSource = ds;

</asp:DropDownList>
<asp:Label id="Label2" runat="server" Width="64px">起始时间</asp:Label>

<asp:Label id="Label3" runat="server">结束时间</asp:Label>
