Question

我有一个名为[SchoolingLevels]的课程，代码如下：

public List<SelectListItem> schoolingLevels = new List<SelectListItem>();

public List<SelectListItem> Populate()
{
        schoolingLevels.Add(new SelectListItem { Text = "Primary incomplete", Value = "Primary incomplete" });
        schoolingLevels.Add(new SelectListItem { Text = "Primary", Value = "Primary" });
        schoolingLevels.Add(new SelectListItem { Text = "Secondary incomplete", Value = "Secondary incomplete" });
        schoolingLevels.Add(new SelectListItem { Text = "Secondary", Value = "Secondary" });
        schoolingLevels.Add(new SelectListItem { Text = "Higher education incomplete", Value = "Higher education incomplete" });
        schoolingLevels.Add(new SelectListItem { Text = "Higher education", Value = "Higher education" });
        schoolingLevels.Add(new SelectListItem { Text = "Post-graduation/MBA", Value = "Post-graduation/MBA" });
        return schoolingLevels;
}

我想基于此List填充我的RadioButton ..

在我的控制器中：

ViewBag.Scholarity = new SchoolingLevels().Populate();

在我看来：

@Html.RadioButton("Scholarity", "a")

它没有工作..（我用DropDown测试并且工作得很好），是不是可以使用RadioButton？

修改

我试过了：

@foreach (var myValue in ViewBag.Scholarity)
{ 
   Html.RadioButton("Scholarity","Value")
}

看起来很有效，但我可以在哪里放置无线电按钮的名称？

Answer 1

您还可以遍历列表并根据您拥有的数据更改下面的代码。

foreach (var item in Model)
{
    @Html.RadioButtonFor(m => m.item, "Yes") @:Yes
    @Html.RadioButtonFor(m => m.item, "No") @:No
}

Answer 2

我认为以下代码可以帮助您：

@foreach (var myValue in ViewBag.Scholarity)
{
    string text = myValue.Text.ToString();
    string val = myValue.Value.ToString();
   @Html.RadioButton("ScholarityList", val);
   <span>@text</span>
}

或创建自定义HTML帮助器，如下所示：

public static MvcHtmlString RadioButtonList(this HtmlHelper helper, 
string NameOfList, List<string> RadioOptions) {

StringBuilder sb = new StringBuilder();

// put a similar foreach here
foreach(var myOption in RadioOptions) {
    sb.Append(helper.RadioButton(NameOfList, myOption));
}

return new MvcHtmlString(sb.ToString());

}

@Html.RadioButtonList("ScholarityList", ViewBag.Scholarity);
