关于在ASP.NET MVC4中利用Html.DropDownListFor的示例

关于在ASP.NET MVC4中利用Html.DropDownListFor的示例

　　一、控制器局部：

　　  public ActionResult PageDetail()

　　        {

　　            var thisList = _sysDepartmentBll.GetAllDepartmentList();//数据源

　　  //减少一条默许数据

　　            var resultList = new List<SelectListItem>

　　            {

　　                new SelectListItem {Text = "--请抉择--", Selected = true, Value = ""}

　　            };

　　  //将数据源减少到resultList汇合中

　　            resultList.AddRange(thisList.Select(thisModel => new SelectListItem

　　            {

　　                Text = thisModel.DepartmentName,

　　                Selected = false,

　　                Value = thisModel.DepartmentId

　　            }));

　　            ViewBag.DepartmentList= GetDepartmentSelectList(_sysDepartmentBll.GetAllDepartmentList());

　　            return View();

　　        }

　　二、PageDetail.cshtml局部

　　@Html.DropDownListFor(m => m.DepartmentId, ViewBag.DepartmentList as IEnumerable<SelectListItem>, new { id = "ddlDepartment"})

　　或许

　　@Html.DropDownListFor(m => m.DepartmentId, (List<SelectListItem>)ViewBag.DepartmentList, new { id = "ddlDepartment"})
