Hi folks,

I'm just venturing out into the world of MVC (v4) and I'm having real trouble getting the actual selected values of a list of radiobutton lists. I'll post everything that I've done so far in the hope that someone more intelligent than I could point me in the right direction:

Here's my content structure:

My Model

namespace ICASolution.Models
{
    public class MultipleChoiceViewModel
    {
        public int iQuestionID { get; set; }
        public string zQuestionTitle { get; set; }
        public string zQuestionText { get; set; }
        public List<Answers> lAnswers { get; set; }

    }

    public class Answers
    {
        public int iAnswerID { get; set; }
        public string zAnswerText { get; set; }
        public bool bCorrect { get; set; }
        public string selectedAnswer { get; set; }
    }
}

My surface controller:

namespace ICASolution.Controllers
{
    public class MultipleChoiceSurfaceController : SurfaceController
    {
        //
        // GET: /MultipleChoiceSurface/

        //public ActionResult Index()
        //{
        //    return PartialView("MultipleChoice", new MultipleChoiceViewModel());
        //}
        [HttpPost]
        public ActionResult Grade(MultipleChoiceViewModel model)
        {

            return RedirectToCurrentUmbracoPage();
        }

        public ActionResult Index()
        {
            var TestPage = Umbraco.Content(CurrentPage.Id);
            var questions = new List<MultipleChoiceViewModel>();

            foreach (var child in TestPage.Children)
            {
                var questionid = child.Id;
                var questiontitle = child.GetPropertyValue("questionTitle");
                var questiontext = child.GetPropertyValue("questionText");

                questions.Add(new MultipleChoiceViewModel { iQuestionID = questionid, zQuestionTitle = questiontitle, zQuestionText = questiontext, lAnswers = answerList(questionid) });

            }

            return PartialView("MultipleChoice", questions);
        }

        public List<Answers> answerList(int iMyQuestionID)
        {
            var questionPage = Umbraco.Content(iMyQuestionID);
            var answers = new List<Answers>();


            foreach(var child in questionPage.Children)
            {
                answers.Add(new Answers { iAnswerID = child.Id, zAnswerText = child.GetPropertyValue("answerTitle"), bCorrect =  child.GetPropertyValue("correctAnswer") });
            }

            return answers;
        }

    }
}

and finally my partial:

@model IEnumerable<ICASolution.Models.MultipleChoiceViewModel>


<div class="ethicsTestContainer">
    <div class="col-md-12">
        <div class="col-md-12 noRPadding">
            @using (Html.BeginUmbracoForm<ICASolution.Controllers.MultipleChoiceSurfaceController>("Grade")) { 

                    foreach (var item in Model)
                    {
                        <div class="form-group">
                            <p><strong>@item.zQuestionTitle</strong></p>
                            <p>@item.zQuestionText</p>

                            @{
                                foreach (var answerItem in item.lAnswers)
                                {
                                    <div class="radio radio-danger">
                                        @Html.RadioButtonFor(model => answerItem.selectedAnswer, answerItem.iAnswerID)

                                        <label for="@answerItem.iAnswerID">
                                            @answerItem.zAnswerText <span>&nbsp;</span>@answerItem.bCorrect
                                        </label>
                                    </div>
                                }
                            }
                        </div>
                    }


                <div class="col-sm-8 col-sm-push-2">
                    <button type="submit" class="btn btn-default btn-block">CLICK HERE TO COMPLETE YOUR ETHICS TEST</button>
                </div>

            }

        </div>
    </div>
</div>

Everything renders fine when displayed to the user:

But I just can't work out how to get the selections that the user has made.

Any help would be greatly appreciated.

Thanks, Craig
