QuestionEnter 3 dates and display order in different VIEW, after click PinmemberxnaLearner7-Dec-12 10:52 
Hey guys so im attempting to throw a project together to increase my knowledge of MVC3 but I have hit a wall...
 
So from my HolidaysController inside my index 'view' I have created a hyperlink which will navigate the user to the 'create3' ActionResult
 
	@Html.ActionLink("Select 3 Dates", "Create3")
-------------------
In my create3 page I want the user to enter 3 dates into text boxes and when they click 'create' the user will be returned to the previous HolidaysController/Index page
where the dates will be displayed in order of ascending date....ATM I have this working up until the user enters 3 dates and clicks 'create'...However I only know
how to display a message box displaying the order, it is working I just need help getting the order to be displayed from the index page.
 
Please see my code:
Code for HolidayController/Index:
--------------
	 //submit will go to post
        [HttpPost]
        public ViewResult Index(int HolidayDate)
        {
            var holidays = db.Holidays.Include("Person");
 
            HolidayList model = new HolidayList();
 
            model.currentPersonID = HolidayDate;
            model.PList4DD = db.People.ToList();           
            model.Categories = holidays.Select(x => new SelectListItem
                                            {
                                                Value = x.Id.ToString(),
                                                Text = x.Person.Name
                                            }
                                          );
 

            int data = HolidayDate;
 
            model.HList4DD = db.Holidays.Where(h => h.PersonId == HolidayDate).ToList();      
 
            return View(model);
 
        }
 
        [HttpGet]
        public ViewResult Index(string sortOrder, int? currentPersonID)
        {
            var holidays = db.Holidays.Include("Person");
 
            HolidayList model = new HolidayList();
 
            //not null
            if (currentPersonID.HasValue)
            {
                model.currentPersonID = currentPersonID.Value;
 
            }
            else
            {
                model.currentPersonID = 0;
            }
 
            model.PList4DD = db.People.ToList();
 
            ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "date" : "";
            var dates = from d in db.Holidays
                        where d.PersonId == currentPersonID.Value
                        select d;
     
            switch (sortOrder)
            {
                case "date":
                    dates = dates.OrderBy(p => p.HolidayDate);
                    break;
            }
