一、非强类型:
Controller:
ViewData["AreId"] = from a in Table
select new SelectListItem {
Text=a.AreaName,
Value=a.AreaId.ToString()
};
View:
@Html.DropDownList("AreId")
还可以给其加上一个默认选项:@Html.DropDownList("AreId", "请选择");
二、强类型:
DropDownListFor常用的是两个参数的重载,第一参数是生成的select的名称,第二个参数是数据,用于将绑定数据源至DropDownListFor
Modle:
public class SettingsViewModel
{
Repository rp =new Repository();
public string ListName { get; set; }
public IEnumerable<SelectListItem> GetSelectList()
{
var selectList = Table.Select(a => new SelectListItem {
Text=a.AreaName,
Value=a.AreaId.ToString()
});
return selectList;
}
}
Controller:
public ActionResult Index()
{
return View(new SettingsViewModel());
}
View:
@model Mvc3Applicationtest2.Models.SettingsViewModel
@Html.DropDownListFor(m=>m.ListName,Model.GetSelectList(),"请选择")
