保存textbox和datagridview中的所有数据

Question

我有一个datagridview，我只想保存产品代码，还有文本框; totalamount，现金，变化。如何将产品代码和文本框值保存到数据库？我尝试了下面的代码，但它只保存了一行。谢谢！

datatable and textboxes

代码：

   Public Sub addTransaction()
        Try
            dbConnection()
            insert_query = "INSERT INTO tbltransactions(trans_number, trans_total, trans_cash, trans_change, trans_date, trans_time, trans_month, trans_day, trans_year, invoice_number, product_code) VALUES(@trans_number, @trans_total, @trans_cash, @trans_change, @trans_date, @trans_time, @trans_month, @trans_day, @trans_year, @trans_invoice, @product_code);"
            command = New SqlCommand
            With command
                .Connection = connection
                .CommandText = insert_query
                .Parameters.Clear()
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_number", .SqlDbType = SqlDbType.VarChar, .Value = CashierView.txtTransactionID.Text})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_total", .SqlDbType = SqlDbType.VarChar, .Value = CashierView.txtTotalAmount.Text})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_cash", .SqlDbType = SqlDbType.VarChar, .Value = CashierView.txtTendered.Text})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_change", .SqlDbType = SqlDbType.VarChar, .Value = CashierView.txtChange.Text})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_date", .SqlDbType = SqlDbType.VarChar, .Value = Date.Now.ToString("MMMM dd, yyyy")})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_time", .SqlDbType = SqlDbType.VarChar, .Value = TimeOfDay.ToString("hh:mm:ss tt")})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_month", .SqlDbType = SqlDbType.VarChar, .Value = Date.Now.ToString("MMMM")})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_day", .SqlDbType = SqlDbType.VarChar, .Value = Date.Now.ToString("dd")})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_year", .SqlDbType = SqlDbType.VarChar, .Value = Date.Now.ToString("yyyy")})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@trans_invoice", .SqlDbType = SqlDbType.VarChar, .Value = CashierView.lblInvoiceNumber.Text})
                .Parameters.Add(New SqlParameter With {.ParameterName = "@product_code", .SqlDbType = SqlDbType.VarChar})
                For Each row As DataGridViewRow In CashierView.ProductsListDGV.Rows
                    If Not row.IsNewRow Then
                        .Parameters("@product_code").Value = row.Cells(0).Value
                        .ExecuteNonQuery()
                    End If
                Next
            End With
        Catch ex As SqlException
            MsgBox("Error: " + ex.Message)
        Finally
            connection.Close()
            command.Dispose()
        End Try
    End Sub
