public ActionResult PageDetail()
{
var thisList = _sysDepartmentBll.GetAllDepartmentList(); //数据源
//添加一条默认数据
var resultList = new List<SelectListItem>
{
new SelectListItem {Text = "--请选择--" , Selected = true , Value = "" }
};
//将数据源添加到resultList集合中
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部分
复制代码 代码如下:
@Html.DropDownListFor(m => m.DepartmentId, ViewBag.DepartmentList as IEnumerable<SelectListItem>, new { id = "ddlDepartment"})
或者:
复制代码 代码如下:
@Html.DropDownListFor(m => m.DepartmentId, (List<SelectListItem>)ViewBag.DepartmentList, new { id = "ddlDepartment"})
希望本文所述对大家asp.net程序设计有所帮助。
