1、下拉框代码方式
控制器内构建下拉项目:
List<SelectListItem> list = new List<SelectListItem>(); list.Add(new SelectListItem() { Text = "计算机", Value = "computer" }); list.Add(new SelectListItem() { Text = "数学", Value = "math" }); ViewData["deptName"] = list;
视图中:
<p>所属部门:@Html.DropDownListFor(m => m.deptName, ViewData["deptName"] as List<SelectListItem>)</p>
2、下拉框数据库方式
控制器内通过数据库构建下拉项目:
ViewData["AreaId"] = from a in rp.GetArea() select new SelectListItem { Text=a.AreaName, Value=a.AreaId.ToString() };
试图中:
<p>所属区域:@Html.DropDownListFor(m => m.AreaID, ViewData["AreaID"] as List<SelectListItem>)</p>
