Question

我有以下linq to sql查询，我绑定到detailsview

            var ShippingChallan = (from sc in db.ShippingChallanViewSeconds
                               where sc.challan_id == Convert.ToDecimal(txtChallanNo.Text) && sc.SecondWeight != null && sc.Type == "LBO"
                               select new { 
                                   sc.challan_id,
                                   sc.bowzer_no,
                                   sc.FirstWeight,
                                   sc.SecondWeight,
                                   sc.netWeight,
                                   sc.Product_Name,
                                   sc.FLD,
                                   sc.Customer_Name,
                                   sc.dip1,
                                   sc.Cmpt_Capacity1,
                                   sc.dip2,
                                   sc.Cmpt_Capacity2,
                                   sc.dip3,
                                   sc.Cmpt_Capacity3,
                                   sc.dip4,
                                   sc.Cmpt_Capacity4,
                                   sc.dip5,
                                   sc.Cmpt_Capacity5
                               }).FirstOrDefault();

在99％的行中，sc.dip4和sc.dip5为空。

如果用户为null，我不想向用户显示这些属性。

我该怎么办？任何想法???

好吧，我自己得到了：这就是我想出来的

DV_ChallanDetails.AutoGenerateRows = false; 
BoundField bow = new BoundField();
bow.DataField = "bowzer_no"; 
bow.HeaderText = "Bowzer No"; 
DV_ChallanDetails.Fields.Add(bow);

我为每个领域做，并且如果任何领域是空的并且只是将其可见属性设置为假
