C# GridView和DataGrid列数据源额外列

我一直在尝试使用数据网格和网格视图

---

使用，
AutoGenerateColumns=“False”


DataGrdBuilding.DataSource = (from k in en.ClientSiteBuildings
                                      where k.ClientSiteId == _ClientSiteId
                                      select new { Building = k.ClientSiteBuildingName }).ToList();
            DataGrdBuilding.DataBind();
