ASP.Net ถ้าต้องการ connect db ใน DataList1_ItemDataBound ต้องทำไงครับ

protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {

        id =  Convert.ToInt16(DataBinder.Eval(e.Item.DataItem, "car_id"));

 string query = "select count(*) from booking  where (NOW() between booking_startDate and booking_endDate) and    booking_confirm_vehicles='อนุมัติ' and car_id =" + id;
        MySqlCommand cmd = new MySqlCommand(query, objConn);   
 result = Convert.ToInt16(cmd.ExecuteScalar());


        string car_status = Convert.ToString( DataBinder.Eval(e.Item.DataItem, "car_status"));
        Image img = (Image)(e.Item.FindControl("imgstatus"));
        if (result >0)
        {
            img.ImageUrl = "~/images/status_green.png";
        }
        else
        {
            img.ImageUrl = "~/images/status_red.png";
        }

    }
