I have these two methods that correctly populate a datagridview. The question is what do I need to add to get any changes committed to the SQL tables in the database? I can change values in the grid but those changes are not being committed to the database.
 
      private void InitializeDataGridView()
        {
            try
            {
                // Set up the data source.
                bindingSourceStations.DataSource = GetData("SELECT [STATIONID] AS 'Station ID',[STATNAME] AS 'Station Name' FROM [WXDATA].[dbo].[STATIONS]");
                dgvStations.DataSource = bindingSourceStations;

                // Automatically resize the visible rows.
                dgvStations.AutoSizeRowsMode =
                    DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders;

                // Set the DataGridView control's border.
                dgvStations.BorderStyle = BorderStyle.Fixed3D;

                // Put the cells in edit mode when user enters them.
                dgvStations.EditMode = DataGridViewEditMode.EditOnEnter;

            }
            catch (SqlException)
            {
                MessageBox.Show("To run this sample replace connection.ConnectionString" +
                    " with a valid connection string to the stations" +
                    " database accessible to your system.", "ERROR",
                    MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
                System.Threading.Thread.CurrentThread.Abort();
            }
        }

        private static DataTable GetData(string sqlCommand)
        {
            string connectionString = DataAccess.ConnectionStringSQL(Controller.Instance.Model.SQLDatabase);

            SqlConnection stationsConnection = new SqlConnection(connectionString);

            SqlCommand command = new SqlCommand(sqlCommand, stationsConnection);
            SqlDataAdapter adapter = new SqlDataAdapter();
            adapter.SelectCommand = command;

            DataTable table = new DataTable();
            table.Locale = System.Globalization.CultureInfo.InvariantCulture;
            adapter.Fill(table);

            return table;
        }
