使用ASP.NET MVC ViewBag和DropDownListfor有困难 [英] Having difficulty using an ASP.NET MVC ViewBag and DropDownListfor

问题描述

我的困难是如何使用 ViewBag 与 DropdownListFor ？

My difficulty is how to use ViewBag with DropdownListFor?

在我的控制器我有：

TestModel model = new TestModel();
ViewBag.Clients = model.Clients;
ViewBag.StatusList = model.StatusList;
ViewBag.enumStatus = model.enumStatus;
ViewBag.intClient = model.intClient;

在我TestModel

In my TestModel

public SelectList Clients { get; set; }       
public SelectList StatusList { get; set; }
public ActiveStatus enumStatus { get; set; }
public int? intClient { get; set; }

在我的视图

我想用 DropDownListFor 显示ViewBag值，我该怎么办呢？

I want to use DropDownListFor to display the ViewBag values, how can I do that?

推荐答案

个人......我创建了一个列表，并做到这一点。

Personally...I create a List and do this.

public ActionResult SomeAction()
{
    var list = new List<SelectListItem>();
    list.Add(new SelectListItem(){Text = "One", Value="One"});
    list.Add(new SelectListItem(){Text = "Two", Value="Two"});
    list.Add(new SelectListItem(){Text = "Three", Value="Three"});
    list.Add(new SelectListItem(){Text = "Four", Value="Four"});

    ViewBag.Clients = list;

    return View();
}

，然后在您的视图...

and then in your view...

@Html.DropDownListFor(x => x.SomePropertyOnModel, (IEnumerable<SelectListItem>)ViewBag.Clients);

注意在Viewbag项目投。演员是必需的，因为viewbag不知道对象是什么 Viewbag.Client 。所以剧组有要求。
