Question

您好以下代码根据网格视图中的产品数量从库存中扣除产品数量，ID = gridagree

问题是我想要使用category = 1扣除产品数量并进行验证，检查所有产品数量是否在gridagree中是否大于库存数量，如果一个产品数量大于stoack中的数量代码不应该执行

Category Id =gridagree.Rows[index].Cells[7].Text

Product Id = gridagree.Rows[index].Cells[3].Text)

Product Quantity in the grid =gridagree.Rows[index].Cells[5].Text

StoreClass s = new StoreClass();

if(//suggested code)
{

lblmsg.Text="Product quantity is bigger than current balance please change product quantity and try again"// here also can i determine to the user which product has the issue product with id=?
}

else
{
for (int index = 0; index < this.gridagree.Rows.Count; index++)
                    {
                        if (gridagree.Rows[index].Cells[7].Text == "1")
                        {
                            string qun = s.getprodqun(Convert.ToInt32(gridagree.Rows[index].Cells[3].Text));
                            s.subtract(Convert.ToInt32(gridagree.Rows[index].Cells[3].Text), Convert.ToInt32(qun) - Convert.ToInt32(gridagree.Rows[index].Cells[5].Text));
                        }

                    }
}
