Question

我将ViewModel定义为：

    public class Fixtures
    {
        public int Id { get; set; }
        public string HomeTeam { get; set; }
        public string AwayTeam { get; set; }
        public string HomeTeamCode { get; set; }
        public string AwayTeamCode { get; set; }
        public string League { get; set; }
        public bool Home { get; set; }
        public bool Draw { get; set; }
        public bool Away { get; set; }
        public string FixturePrediction { get; set; }
    }

我的视图显示了这些灯具的列表，对于每个灯具，我有一个单选按钮分组。我需要一些方法将每个灯具的选定单选按钮传递给我的Post方法。我的视图和控制器如下：

查看：

<div class="container">
    @using (Html.BeginForm())
    {
        @Html.AntiForgeryToken()
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

        for (int i = 0; i < Model.Count(); i++)
        {
            @Html.HiddenFor(model => model[i].Id)

            <div class="col-sm-6">
                <div class="panel panel-primary panel-fixture">
                    <div class="panel-heading text-center fixturetitle">
                        @Html.DisplayFor(model => model[i].HomeTeam) v @Html.DisplayFor(model => model[i].AwayTeam)
                        @Html.HiddenFor(model => model[i].HomeTeam)
                        @Html.HiddenFor(model => model[i].AwayTeam)
                    </div>
                    <div class="panel-body">
                        <div class="container-fluid">

                                    <div class="text-center">
                                        @Html.DisplayFor(model => model[i].HomeTeamCode)

                                    </div>
                                </div>

                                    </label>
                                </div>
                                <div class="col-xs-4 text-center">

                                            @Html.RadioButtonFor(model => model[i].FixturePrediction, Model[i].Home, new { @Name = Model[i].Id })
                                            @Html.HiddenFor(model => model[i].FixturePrediction)

                                    <div class="col-xs-4 text-center">

                                            AWAY
                                            @Html.RadioButtonFor(model => model[i].FixturePrediction, Model[i].Away, new { @Name = Model[i].Id })
                                            @Html.HiddenFor(model => model[i].FixturePrediction)

                </div>
            </div>
        }
        <input type="submit" value="Confirm Predictions" class="btn btn-success" />
    }
</div>

控制器中的帖子方法：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Test(IEnumerable<Fixtures> test)
{
    if (ModelState.IsValid)
    {

    }

    return RedirectToAction("Test");
}

我的字段FixturePrediction始终为空，我尝试了上面显示的'radiobuttonfor'的几种变体。

我需要的是根据选择的单选按钮为FixturePrediction指定一个值。我错过了什么？

提前致谢。

Answer 1

我认为你要做的就是这个，我不确定你为什么这样做，但这就是你实现Html.RadioButtonFor的方式，它需要模型道具，以及值，您可以根据需要添加任意数量的按钮，所选的无线电值将作为模型道具的值传递

@Html.RadioButtonFor(model => model[i].FixturePrediction, "Home")
 @Html.RadioButtonFor(model => model[i].FixturePrediction, "Draw")
 @Html.RadioButtonFor(model => model[i].FixturePrediction, "Away")

Another example

无法将RadioButton组选定值传递给Controller
