winform循环绑定combox的值到datagradeview上并显示

[qq_40905926]

if (cmbCreateGoodName.SelectedItem.ToString().Equals("全部") && !cmbCreateGoodKind.SelectedItem.ToString().Equals("全部"))
{

BindColumnDelOrder("单品汇总1");
if (string.IsNullOrEmpty(cmbCreateGoodName.Text))
{
MessageBox.Show("请选择商品！");
return;
}
_listgoodinfos = Service.GetAllSaleGoods(cmbCreateGoodKind.Text).ToList();
for (int i = 0; i < _listgoodinfos.Count; i++)
{
string startTime = "";
string endTime = "";
string timeType = null;
string GoodName = null;
GoodName = _listgoodinfos[i].ToString();
startTime = dtpStart.Value.ToString("yyyy-MM-dd 00:00:00");
endTime = dtpEnd.Value.ToString("yyyy-MM-dd 23:59:59");
timeType = cmbTimeType.Text.ToString();

List<OrderGoodsReport> OrderGoodsList = Service.GetOrderGoodStatistics_1(timeType, startTime, endTime, GoodName, cmbOrderStatus.Text, comboBox1.Text, false).ToList();


if (OrderGoodsList.Count() < 1)
{
return;
}


float TotalSpecification = 0.00F; //磅数
int TotalQuantity = 0; //个数
int Goods_Specification = 0;//订单数

for (int j = OrderGoodsList.Count - 1; j > -1; j--)
{
TotalSpecification += OrderGoodsList[j].TotalSpecification;
TotalQuantity += int.Parse(OrderGoodsList[j].TotalQuantity.ToString());
Goods_Specification += int.Parse(OrderGoodsList[j].Goods_Specification.ToString());
}



OrderGoodsReport OrderGoods = new OrderGoodsReport();
OrderGoods.Goods_Name = "总计";
OrderGoods.TotalSpecification = TotalSpecification;
OrderGoods.TotalQuantity = TotalQuantity;
OrderGoods.Goods_Specification = Goods_Specification;
OrderGoodsList.Add(OrderGoods);

dgvShow.DataSource = OrderGoodsList;

}

}

目前只能绑定combox中的一个值，并不能绑定所有值
