datagrid绑定list没有数据 表头不显示的问题
那是因为 绑定了null
你给list new一下就好 表头就会有啦
var list = Pt_OrderWorkFlow_DAO.GetOrderWorkFlow(wfid, uid, 1); if (list == null) { list = new List<Pt_OrderWorkFlow>(); } dgWaitList.DataSource = list; dgWaitList.DataBind();
可以直接这样比较优雅了
OADataContext db = DatabaseHelper.GetDB(); var rs = (from a in db.Pt_OrderWorkFlow where a.WFID == wfID && a.ContractNumber == cNumber select a).ToList<Pt_OrderWorkFlow>(); return rs.Count() > 0 ? rs : new List<Pt_OrderWorkFlow>();
