DataGridVirew保存问题中的多个项目

Question

我有一个名为PurchaseInvoiceForm的表格。当我在DataGridView中添加多个产品时，它具有许多产品。他从不保存所有项目，但显示出一些错误。我有一个我创建的DLL 用于数据保存|检索并对其执行一些其他操作。这是我使用的以下代码。

这是我单击“保存按钮”时的第一件事。

private void SaveMetroTile_Click(object sender, EventArgs e)
    {
        if (IsFormOk())
        {
            if (this.IsUpdate)
            {
                //Do Update Process
                SaveOrUpdateStock("usp_PurchaseInvoiceSaveOrUpdateStockDetails");
                ShowSucessMessage("Purchase Invoice Has Been Updated Successfully");
            }
            else
            {
                //Do Save Process
                SaveOrUpdateStock("usp_PurchaseInvoiceSaveOrUpdateStockDetails");
                ShowSucessMessage("Purchase Invoice Has Been Added Successfully");
            }

        }

    }

这是用于保存或更新接受存储过程和对象的记录的方法。

    private void SaveOrUpdateStock(string storedProceName)
    {
        DbSQLServer db = new DbSQLServer(AppSetting.ConnectionString());
        db.SaveOrUpdateRecord(storedProceName, GetObject());
    }
    private StockDetails GetObject()
    {
        StockDetails stock = new StockDetails();
        try
        {     
            stock.ProcessType = (this.IsUpdate) ? (int)ProcessType.Update : (int)ProcessType.Save;
            stock.PurchaseInvoiceId = (this.IsUpdate) ? this.Id : 0; //Zero Means No Id Just Save
            stock.PurchaseInvoiceNo = Convert.ToInt32(InvoiceNoMetroTextBox.Text.Trim());
            stock.PurchaseInvoiceDate = PurchaseInvoiceDateMetroDateTime.Value.Date;

            stock.InvoiceNo = Convert.ToInt32(PurchaseInvoiceNoMetroTextBox.Text.Trim());
            stock.InvoiceDate = PurchaseInvoiceDateMetroDateTime.Value.Date;

            stock.PartyId =Convert.ToInt32(PartyNameMetroComboBox.SelectedValue);
            stock.FromCity = Convert.ToInt32(FromCityMetroComboBox.SelectedValue);
            stock.ToCity = Convert.ToInt32(ToCityMetroComboBox.SelectedValue);


            foreach (DataGridViewRow row in PurchaseInvoiceMetroGrid.Rows)
            {   
                stock.ProductName= row.Cells["ProductName"].Value.ToString();
                stock.ProductCode = Convert.ToInt32(row.Cells["ProductCode"].Value);
                stock.Box = Convert.ToDecimal(row.Cells["Box"].Value);
                stock.Quantity = Convert.ToInt32(row.Cells["Quantity"].Value);
                stock.UnitPrice = Convert.ToInt32(row.Cells["Price"].Value);
                stock.DiscountInPercent = Convert.ToDecimal(row.Cells["DiscountInPercent"].Value);
                stock.DiscountAmount = Convert.ToDecimal(row.Cells["DiscountAmount"].Value);
                stock.Amount = Convert.ToDecimal(row.Cells["Amount"].Value);
            }

            stock.SubTotal =Convert.ToDecimal(SubTotalMetroTextBox.Text.Trim());
            stock.DiscountedAmount = Convert.ToDecimal(DiscountedAmountMetroTextBox.Text);
            stock.DiscountPercentage = Convert.ToDecimal(DiscountPercentageMetroTextBox.Text);
            stock.Tax = Convert.ToInt32(TaxMetroTextBox.Text.Trim());
            stock.Freight = Convert.ToInt32(FreightMetroTextBox.Text.Trim());
            stock.NetAmount = Convert.ToDecimal(NetAmountMetroTextBox.Text.Trim());

            stock.AllFreight =Convert.ToDecimal(AllFreightMetroTextBox.Text.Trim());
            stock.AllTax = Convert.ToDecimal(AllTaxMetroTextBox.Text.Trim());

            stock.DriverName = DriverNameMetroTextBox.Text.Trim();
            stock.Mobile = MobileMetroTextBox.Text.Trim();
            stock.Vehicle = VehicleNoMetroTextBox.Text.Trim();
            stock.Remarks = RemarksMetroTextBox.Text.Trim();

            stock.LastUpdatedBy = LoggedInUser.UserName;
            stock.CreatedBy = LoggedInUser.UserName;

        }
        catch(Exception ex)
        {
            ShowErrorMessage("Error : " + ex.Message);
        }
        return stock;
    }
