MVC通过UIHint和自定义视图显示RadioButtonList

在Product类中有一个显示删除状态的属性DelFlag，在编辑视图页，对于所有的删除状态以RadioButtonList显示出来，如果RadioButtonList选项的value值与当前model的DelFlag属性值相同，则勾选该选项，如图：

思路：

→在Views/Shared/EditorTemplates/RadioButtonList.chtml部分视图以RadioButtonList呈现所有删除状态。
→在编辑视图中，需要把有关删除状态，封装成List<SelectListItem>放在路由中传递给部分视图RadioButtonList.chtml
→在Product的DelFlag属性上，通过[UIHint("RadioButtonList")]指定该属性的显示视图

public class Product
    {
        [UIHint("RadioButtonList")]
        public int? DelFlag { get; set; }
    }

HomeController:

public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View( new Product(){DelFlag = 2});
        }

}

Home/Index.cshtml视图：

其中，关于删除状态，封装成List<SelectListItem>，并通过路由传递给接收的部分视图。

@model MvcApplication2.Models.Product

@{

    ViewBag.Title = "Index";

    Layout = "~/Views/Shared/_Layout.cshtml";

    List<SelectListItem> list = new List<SelectListItem>();

    list.Add(new SelectListItem(){Text = "正常使用",Value = "1"});

    list.Add(new SelectListItem() { Text = "逻辑删除", Value = "2" });

    list.Add(new SelectListItem() { Text = "物理删除", Value = "3" });

}

<style type="text/css">

    ul{

        list-style-type: none;

    }

</style>

<h2>Index</h2>
