Mapmvcattributeroutes with Pagedlist.MVC

Question

I’m using the routes.MapMvcAttributeRoutes(); to decorate my actions with the Url I want to appear in the browser, and it has worked very well, however, when using with the PagedList I’ve been having a problem that I can’t solve.

below follows the code of my controller:

    [Route("sala-de-impresa/noticias/{page?}")]
    public ActionResult Noticia(int? page)
    {
        var model = _ctx.Noticias.Include("Categoria").Where(n => n.Status && n.DataPublicacao <= DateTime.Now).OrderByDescending(n => n.NoticiaId);

        const int pageSize = 20;
        var pageNumber = (page ?? 1);
        return View(model.ToPagedList(pageNumber, pageSize));
    }

Here is the View code that makes the pagination:

@Html.PagedListPager(Model, page => Url.Action("Noticia", new { page, currentFilter = ViewBag.CurrentFilter }), PagedListRenderOptions.OnlyShowFivePagesAtATime)

To the Home page the Url and accessed smoothly,

Ex: localhost:xxxx/newsroom/newsroom

But when trying to advance the pagination to page 2 for example:

localhost:xxxx/newsroom/2

get the bug:

Erro de Servidor no Aplicativo '/'.

But if I edit the Url and put it like this:

localhost:xxxx/newsroom/newsroom? page=2

Paging works normally.

EDIT:

Controller Noticia and Salaimpresa code

public class SalaImprensaController : Controller
    {
        readonly AmeronContext _ctx = new AmeronContext();

        [Route("sala-de-impresa/noticias/{page?}")]
        public ActionResult Noticia(int? page)
        {
            var model = _ctx.Noticias.Include("Categoria").Where(n => n.Status && n.DataPublicacao <= DateTime.Now).OrderByDescending(n => n.NoticiaId);

            const int pageSize = 20;
            var pageNumber = (page ?? 1);
            return View(model.ToPagedList(pageNumber, pageSize));
        }

        [Route("sala-de-impresa/videos")]
        public ActionResult Videos(int? page)
        {
            var model = _ctx.Videos.ToList().OrderByDescending(n => n.VideoId).ToList();

            const int pageSize = 9;
            var pageNumber = (page ?? 1);
            return View(model.ToPagedList(pageNumber, pageSize));
        }

        [Route("sala-de-impresa/galerias/{page?}")]
        public ActionResult Galerias(int? page)
        {

            var widget = _ctx.Noticias.Include("Categoria").ToList().Where(n => n.Categoria.Nome == categoria && n.Status).OrderByDescending(n => n.NoticiaId).Take(15);

            ViewBag.Noticia = noticia;

            return View(widget);
        }

Answer 1

Modification:

@Html.PagedListPager(Model, page => Url.Action("Noticia", "Noticia", new { page = page, currentFilter = ViewBag.CurrentFilter }), PagedListRenderOptions.OnlyShowFivePagesAtATime)

In the Url.Action if you can put the Controller and the Action that he picks up from routing automatically, I based that controller is News story and its action is News story, if it is not change in Url.Action being the first to Action and the second Controller, then comes the new that are pagination and filter ...

Error:

Duplication of Routing

The request has found the following types of matching controllers:

• WP_AMERON.Controllers.NoticiaController
• WP_AMERON.Controllers.SalaImprensaController

There is a routing in Noticiacontroller [Route("{categoria}/{id}/{titulo}")] that ta interfering on their routes, because, the keys represent variables and were matching with the other routes that has this layout ...

Answer 2

The problem was in a conflict between another Controller’s route. My route from the Controller SalaImprensa:

[Route("sala-de-impresa/noticias/{page?}")]

It was conflicting with the Controller’s route Noticia:

[Route("{categoria}/{id}/{titulo}")]

I found with the help of @Ffcdias and solved the problem by adding a name before the parameters of my route in Controller Noticia:

[Route("sala-de-imprensa/{categoria}/{id}/{titulo}")]
