asp.net-mvc - 一种在 aspnetboilerplate 中进行分页和排序的简单方法

Question

是否有任何简单的方法可以在 ASP.NET 样板解决方案中的表示层中实现分页，例如 PagedList.Mvc Nuget 包中的 PagedList 。

我从 Nuget gallery 安装了 PagedList.Mvc 包，并将我的 Index 方法更改为:

 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);
        }

在 View 中，我将其添加到新闻表下:

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

但是当我单击数字(例如数字 2 或 3)时，表格会刷新但会更改数据。

ASP.NET Boilerplate 不提供此功能，但按照您的建议使用 PagedList.Mvc 很简单。

很容易修改UsersController.Index使用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);
}
