Question

我已经阅读了关于这个问题的几个问题和答案，但没有一个让我更接近解决这个问题。我的问题是我似乎无法将RadioButtonFor检查值保留到post action方法。它有很多不相关的东西，所以我会尝试将其归结为相关问题。

所以我有ViewModel这样：

    public class QEventHandlerVM
    {
       //Removed unrelated
       public QueueEventHandlerModel QEventHandler { get; set; }           
       public string SelectedOption { get; set; }
    }

编辑视图的Get Method。我在这里设置SelectedOption所以我可以在前端处理它。任务是根据SelectedOption值显示和隐藏div。据我所知，这部分工作，值已设置并通过jQuery在视图中使用。

    [HttpGet]
    public ActionResult Edit(int id)
    {
        try
        {
            //Removed unrelated...
            QueueEventHandlerModel model;
            QEventHandlerVM vm = new QEventHandlerVM();

            ApiCommunicator.Get("QueueEventHandlers/" + id, out model);

            vm.QEventHandler = model;
            if (...)                
                vm.SelectedOption = "toQueue";

            if (...)                
                vm.SelectedOption = "redirection";

            if (...)
                vm.SelectedOption = "hangup";

            return View(vm);
        }
        catch (HttpResponseUnsuccessfulException e){...}

    }

Edit view简化：

        @model Foo.WebSites.Web.Views.QueueEventHandlers.QEventHandlerVM

        @using (Html.BeginForm())
        {
            @Html.AntiForgeryToken()

            //Unrelated stuff...
            @Html.HiddenFor(s => s.SelectedOption)

            @Html.RadioButtonFor(s => s.SelectedOption, "toQueue", new { id = "rdToQueue", @class = "q-event" })
            <label for="rdToQueue">Transfer call to queue</label>

            @Html.RadioButtonFor(s => s.SelectedOption, "redirect", new { id = "rdRedirect", @class = "q-event" })
            <label for="rdRedirect">Transfer call to destination</label>

            @Html.RadioButtonFor(s => s.SelectedOption, "hangup", new { id = "rdHangup", @class = "q-event" })
            <label for="rdHangup">Hangup</label>

            <button type="submit" class="btn btn-primary btn-sm">Save</button>
        }

Post方法

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit(QEventHandlerVM model, int id)
    {
        if (!ModelState.IsValid) {... return View(model); }

        if (model.SelectedOption == "hangup" || model.SelectedOption == "redirection")
        {
            model.QEventHandler.QueueId = null;
        }
        else if (model.SelectedOption == "toQueue")
        {
            model.QEventHandler.Phrase = string.Empty;
            model.QEventHandler.Redirection = string.Empty;
        }
        else if (model.SelectedOption == "hangup")
        {
            model.QEventHandler.Redirection = string.Empty;
            model.QEventHandler.QueueId = null;
        }

        try {// Update}
        catch (HttpResponseUnsuccessfulException e){...}
    }

现在，SelectedOption值与Get方法的值相同。我可能已经错过了一些简单的事情，并且最有可能采取更好的方式。

提前致谢。

这是因为您的HiddenFor媒体资源的SelectedOption 和相关编辑字段。只需删除HiddenFor，这应该有效：

@Html.HiddenFor(s => s.SelectedOption)

MVC 5将单选按钮字符串值发送到post action方法
