Question

ASP.NET MVC 视图里面的下拉框怎么动态显示数据库里的数据??

Answer 1

public ActionResult TestDropDownList()
{

List<SelectListItem> lists = new List<SelectListItem>();
lists.Add(new SelectListItem { Text = "001", Value = "111" });
lists.Add(new SelectListItem { Text = "002", Value = "222" });
lists.Add(new SelectListItem { Text = "003", Value = "333" });
lists.Add(new SelectListItem { Text = "004", Value = "444" });

ViewData["lists"] = lists;
ViewData["selected"] = 444;
ViewData["text"] = "CHLH";
return View();
}
========================
下拉框：
@Html.DropDownList("lists")
<br />
@Html.DropDownList("selected",ViewData["lists"] as IEnumerable<SelectListItem>)
================
关键还是lists吧！~

Controller读取出来扔到ViewBag里面就好了啊
