Connection must be valid and open

Question

Hi, I am using a method which get me a list of items from database. I already used the connection to insert data to database and works fine, but when displaying data in gridview an exception pops up. Below you can find the method used, the code for binding data to gridview and the asp for the gridview. Hope you can help. Thanks

Method to retreive data

ublic List<Bet> getBets()

        {

            MySqlCommand cmd = Connection.CreateCommand();

            cmd = new MySqlCommand("SELECT * FROM bets ORDER BY date");

            try

            {

                if (this.Connection.State == ConnectionState.Closed)

                    this.Connection.Open();

                MySqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);

                List<Bet> bets = new List<Bet>();

                while (dr.Read())

                {

                    Bet myBet = new Bet();

                    myBet = FillBetfromRow(dr);

                    bets.Add(myBet);

                }

                return bets;

            }

            catch (MySqlException ex)

            {

                throw ex;

            }

            finally

            {

                if (Connection.State == ConnectionState.Open)

                    Connection.Close();

            }

        }
