RadioButtonFor组不允许选择更改

Question

我正在生成一个单选按钮组，以使用MVC＆Razor和强类型视图在页面显示中显示选择选项。虽然循环有效，但我无法将单选按钮组的选择从控制器返回的数据更改为第二个值。我的HTML / Razor标记/代码如下：

@model IEnumerable<XXXX.App.Models.SettingsModel>

@{
    ViewBag.Title = "Application Settings";
}
@using (Html.BeginForm("Index", "Settings", FormMethod.Post))
{
    <div class="container body-content">
            <div id="settings-page" class="row">
                <div class="row">
                    <div class="input-field col l12 m12 s12 center">
                        <p class="center collection-header">Application Settings.</p>
                    </div>
                </div>
                <table class="striped">
                    @foreach (var item in Model)
                    {
                        <tr>
                            <td>
                                @if (item.CONFIG_TYPE != 4)
                                {
                                    @Html.DisplayFor(modelItem => item.CONFIG_NAME)
                                }
                                else
                                {
                                <strong>@Html.DisplayFor(modelItem => item.CONFIG_NAME)</strong>
                                }
                            </td>
                            <td>
                                @{
                                    switch (item.CONFIG_TYPE)
                                    {
                                        case 1:
                                            //@Html.TextBoxFor(modelItem => item.CONFIGURATION_VALUE, "{0:c}", new { @id = item.URN.ToString(),  @class = "input-field col l4 m4 s12", Title = item.CONFIG_DESCRIPTION, Type = "number" })
                                            break;
                                        case 2:
                                            //@Html.TextBoxFor(modelItem => item.CONFIGURATION_VALUE, null, new { @id = item.URN.ToString(),  @class = "input-field col l4 m4 s12", Title = item.CONFIG_DESCRIPTION, Type = "text" })
                                            break;
                                        case 3:
                                            @Html.RadioButtonFor(modelIten => item.CONFIGURATION_VALUE, "1", new { @id = item.URN.ToString() + "_0", @class = "with-gap", @title = item.CONFIG_DESCRIPTION, Type = "radio"})@Html.Label("Yes")
                                            @Html.RadioButtonFor(modelIten => item.CONFIGURATION_VALUE, "0", new { @id = item.URN.ToString() + "_1", @class = "with-gap", @title = item.CONFIG_DESCRIPTION, Type = "radio"})@Html.Label("No")
                                            break;
                                        case 4:
                                            break;
                                    }
                                }
                            </td>
                        </tr>
                    }
                </table>
                <br/>
                <div class="row center">
                    <input id="saveChanges" type="submit" value="Save" title="Save Changes." class="btn waves-effect waves-light center-align" />
                </div>
        </div>

视图生成的HTML如下：

<form action="/Settings" method="post">
  <div class="container body-content">
    <div id="settings-page" class="row">
      <div class="row">
        <div class="input-field col l12 m12 s12 center">
          <p class="center collection-header">Application Settings.</p>
        </div>
      </div>
      <table class="striped">
        <tr>
          <td>
            <strong>Account Lockout</strong>
          </td>
          <td>

          </td>
        </tr>
        <tr>
          <td>
            Invalid Login Count </td>
          <td>
            <input Type="radio" checked="checked" class="with-gap" id="da352600-8342-445c-9b9e-d27725ada4f8_0" name="item.CONFIGURATION_VALUE" title="Account lockout maximum number of invalid logins permitted within the Invalid Login Window." type="radio" value="1"
            /><label for="Yes">Yes</label><input Type="radio" class="with-gap" id="da352600-8342-445c-9b9e-d27725ada4f8_1" name="item.CONFIGURATION_VALUE" title="Account lockout maximum number of invalid logins permitted within the Invalid Login Window."
              type="radio" value="0" /><label for="No">No</label>
          </td>
        </tr>
        <tr>
          <td>
            Invalid Login Window </td>
          <td>

          </td>
        </tr>
      </table>
      <br/>
      <div class="row center">
        <input id="saveChanges" type="submit" value="Save" title="Save Changes." class="btn waves-effect waves-light center-align" />
      </div>
    </div>
  </div>
</form>

我注意到生成的所有控件都使用相同的名称（item.CONFIGURATION_VALUE），但是我希望它们使用数据集中的实际值吗？我误会什么？

只要有需要，这就是控制器的代码：

public async Task<ActionResult> Index(SettingsModel model)
    {
        ApiHandler api = new ApiHandler();
        CookieData cookie = new CookieData();

        // get the company configuration settings from the web api
        HttpResponseMessage response = await api.ReturnApiHttpClient(true).GetAsync("Settings/ReturnCompanyConfig?companyURN=" + cookie.ReturnCompanyURN());

        // check that the response received is valid
        api.CheckHttpResponse(response);

        // check that we have received company settings back
        string result = response.Content.ReadAsStringAsync().Result.ToString();
        if (result.Length == 0)
        {
            TempData["popupMessage"] = "Error.|Unable to get the company identifier for the logged in user.";
            TempData["popupScript"] = "popup.mPopup('open');";
            return RedirectToAction("Index", "Home");
        }

        // convert the json result into the model and return the view with the model
        return View(api.ConvertJsonToModel<SettingsModel>(result));
    }
}
