Order by date asp.net MVC 5

问题

I have a application that creates News Entries and displays 10 news. It should display the 10 "newest" news. As it is now it display the 10 oldest news.

How can I change that.. Do I change the controller so that the data is sorted by date? Or can I do it in the view?

Controller:

public ActionResult Index()
        {
            return View(db.News.ToList());
        }

 // GET: /Newss/Create
        public ActionResult Create()
        {
            return View();
        }

        // POST: /Newss/Create
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see http://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create([Bind(Include="ID,title,body,category,dateCreated")] News news)
        {
            if (ModelState.IsValid)
            {
                news.dateCreated = DateTime.Now;
                db.News.Add(news);
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(news);
        }

It's best to do this in your controller:

public ActionResult Index()
{
    return View(db.News.OrderByDescending(news => new.dateCreated).Take(10).ToList());
}

This way, you get the data sorted from the DB. In general, you should probably keep the view as 'codeless' as possible.

Use the below code to display 10 latest news:

public ActionResult Index()
{
return View(db.News.OrderByDescending(news => new.dateCreated).Take(10).ToList());
}

The above answers are great and work on the controller side. If you, for whatever reason, wanted to do it in the view, this is how it's done:

Ordering Model in View

@foreach (var item in Model.OrderBy(item => item.PostedDate))
{
   <tr>
     <td>
        @Html.DisplayFor(modelItem => item.Id)
     </td>
     <td>
        @Html.DisplayFor(modelItem => item.PostedDate)
     </td>
     <td>
        @Html.DisplayFor(modelItem => item.SomethingAmazing)
     </td>
   </tr>
}
