返回信息流大神给写个语句吧。。。。。
cmdtxt = "SELECT * FROM S_goodsSelection WHERE S_OrderID='" + order_id + "'";
dt_goods = SqlBaseClass.getInstance().GetTable(cmdtxt);
dg_goodslist.DataSource = dt_goods;
//dg_goodslist.Refresh();
if (!dg_goodslist.Columns.Contains("colOperate"))
{
DataGridViewButtonColumn dgvc = new DataGridViewButtonColumn();
dgvc.Name = "colOperate";
dgvc.UseColumnTextForButtonValue = true;
dgvc.Text = "将该商品移出订单";
dgvc.HeaderText = "操作";
dg_goodslist.Columns.Add(dgvc);
dgvc = new DataGridViewButtonColumn();
dgvc.Name = "colOperate_decrease";
dgvc.UseColumnTextForButtonValue = true;
dgvc.Text = "-";
dgvc.HeaderText = "";
dg_goodslist.Columns.Add(dgvc);
dgvc = new DataGridViewButtonColumn();
dgvc.Name = "colOperate_increase";
dgvc.UseColumnTextForButtonValue = true;
dgvc.Text = "+";
dgvc.HeaderText = "";
dg_goodslist.Columns.Add(dgvc);
}
