Any of those help I have a Database table which holds number of Question rows. so I'm using this form to get questions from the database, when I press the the 'Next' Button it works perfectly. but when I press the 'Prev' button it will always go to the first Question. I need this to go to the previous Question. This is how my form looks like: , This
code :
return RedirectToActionPermanent("Index", q)
[HttpGet]
public ActionResult Index(int? qid)
{
    int index = qid == null ? 1 : qid;

    IQuestionService ser = new QuestionService();
    QuestionLoadDTO q = ser.GetIndividualQuestions(index);
    //ViewBag.question = q;
    return View(q);
}
public ActionResult PrevIndex(QuestionLoadDTO ques)
{
    int count1 = 0;
    count1 = int.Parse(Request["qid1"].ToString());
    count1--;
    if (count1 < 5 || count1 >= 0)
    {
        return RedirectToAction("Index", count1);
    }
    return RedirectToAction("End");
}

hop of those help? That's what forms are for. Please note that it is a separate request and you can embed all you data as form fields in the view. Once the user clicks on submit, all the fields of the form will be available in the params hash in the controller action (to which the form is submitted)

may help you . It would be a lot lot better if you use AJAX. This is what it precisely does.
code :
var formDatas = $('#form').serialize();
$.ajax({
    type : 'POST',
    url : 'url',
    data : {formdata : formDatas },
    success: function(result){
      //update the view with the result
    }

}

Hope this helps I am working on a basic alarm app. This is how the main storyboard looks like , You could use a protocol:
code :
protocol DateShare {
    func share(date: NSDate)
}
delegate: DateShare!
customAlert.delegate = self
extension ViewController: DateShare {
    func share(date: NSDate) {
         // do whatever you can for that the date can be displayed in table view 
        alarmDates.append(date) // if I understood it all ?
    }
}
@IBOutlet func addButton(sender: UIButton?) {
    // generate inputDate here
    delegate.share(date: inputDate)
}
