a simple approach for paging and sorting in aspnetboilerplate

Question

is there any simple way for implementing paging in presentation layer in asp.net boilerplate solution like PagedList in PagedList.Mvc Nuget package.

I installed PagedList.Mvc package from Nuget gallery and change my Index method to this :

 public async Task<ActionResult> Index(int? page)
        {
            var pageIndex = (page ?? 1) - 1; //NewsService expects a 0 for the first page
            var pageSize = 3;
            int totalUserCount; // will be set by call to GetAllNews due to _out_ paramter :-|
            var newsResult = await _newsAppService.GetAllNews(new PagedResultRequestDto { MaxResultCount = pageSize });
            totalUserCount = newsResult.TotalCount;

            var news = newsResult.Items;
            var newsAsIPagedList = new StaticPagedList<NewsDto>(news, pageIndex + 1, pageSize, totalUserCount);

            ViewBag.OnePageOfNews = newsAsIPagedList;


            var model = new NewsListViewModel
            {
                News = news
            };

            return View(model);
        }

and in View I add this under the news table :

@Html.PagedListPager((IPagedList)ViewBag.OnePageOfNews, page => Url.Action("Index", new { page }))

but when i click on number for example number 2 or 3 the table refresh but change data.

ASP.NET Boilerplate doesn't provide this, but it's simple to use PagedList.Mvc as you suggested.

It's easy to modify UsersController.Index to use manual paging:

public async Task<ActionResult> Index(int? page)
{
    var pageIndex = (page ?? 1) - 1;
    var pageSize = 10;
    int totalUserCount;

    var skipCount = pageIndex * pageSize;
    var pagedResult = await _userAppService.GetAll(new PagedResultRequestDto { MaxResultCount = pageSize, SkipCount = skipCount });
    totalUserCount = pagedResult.TotalCount;

    var users = pagedResult.Items;
    var usersAsIPagedList = new StaticPagedList<UserDto>(users, pageIndex + 1, pageSize, totalUserCount);

    ViewBag.OnePageOfUsers = usersAsIPagedList;

    // Code below unchanged
    var roles = (await _userAppService.GetRoles()).Items;
    var model = new UserListViewModel
    {
        Users = users,
        Roles = roles
    };
    return View(model);
}
