Question

I m New to ASP. NET MVC 3. 我试图在下降的名单上展示一些选择。这些备选办法将具有奇妙的价值观。该表有三个价值:

public enum Gender 
{
  Male = 0,
  Female = 1,
  NotSpecified=-1
}

我正试图产生以下超文本:

<select>
  <option value="0">Male</option>
  <option value="1">Female</option>
  <option value="2">Not Specified</option>
</select>

我试图与拉扎尔一道这样做,但损失了一点。目前,我有:

@Html.DropDownList("relationshipDropDownList", WHAT GOES HERE?)

请注意,我不能ed。感谢你的帮助!

Answer 1

......

//add this to your view model
IEnumerable<SelectListItem> genders = Enum.GetValues(typeof(Gender))
    .Cast<Gender>()
    .Select(x => new SelectListItem
    {
        Text = x.ToString(),
        Value = x.ToString()
    }); 

@Html.DropDownList("relationshipDropDownList", Model.genders)

Answer 2

同一问题的答复是。

接受的回答有一种延伸方法,将遗体转换成一个选定的清单,可像这样使用。

控制器

ViewBag.Relationships = Gender.ToSelectList();

部分

@Html.DropDownList("relationshipDropDownList", ViewBag.Relationships)

Answer 3

@Html.DropDownList("relationshipDropDownList", Model.GenderSelectList);

不过,我将使用<条码>DropDownListFor,以避免使用魔,:

@Html.DropDownListFor(m => m.relationshipDropDownList, Model.GenderSelectList);

和ViewModel 页: 1 选择性轨道

public static List<SelectListItem> GenderSelectList
{
    get
    {
        List<SelectListItem> genders = new List<SelectListItem>();

        foreach (Gender gender in Enum.GetValues(typeof(Gender)))
        {
            genders.Add(new SelectListItem { Text = gender.ToString(), Value = gender.ToString("D"), Selected = false });
        }

        return genders;
    }
}

Answer 4

    public enum EnumGender
    {
        Male = 0,
        Female = 1,
        NotSpecified = -1
    }


@Html.DropDownList("relationshipDropDownList", (from EnumGender e in Enum.GetValues(typeof(EnumGender))
                                                               select new SelectListItem { Value = ((int)e).ToString(), Text = e.ToString() }), "select", new { @style = "" })



//or

@Html.DropDownList("relationshipDropDownList", (from EnumGender e in Enum.GetValues(typeof(EnumGender))
                                                               select new SelectListItem { Value = ((int)e).ToString(), Text = e.ToString() }), null, new { @style = "" })
