asp.net mvc分页标签

asp.net mvc5 一个关于 分页标签的实例，非常实用

using System.Collections.Generic;using System.Linq;using System.Web.Mvc;using ShowPin.MvcPaging.Demo.Models;namespace ShowPin.MvcPaging.Demo.Controllers{ public class PagingController : Controller { int _currentPage = 1; int _pageSize = 10; private readonly string[] _allCategories = { "吃的", "穿的", "用的" }; private readonly IList<Product> _allProducts = new List<Product>(); public PagingController() { InitializeProducts(); } //简单初始化产品集合 private void InitializeProducts() { for (var i = 0; i < 122; i ) { var product = new Product { Name = "产品 " (i 1) }; var categoryIndex = i % 4; if (categoryIndex > 2) { categoryIndex = categoryIndex - 3; } product.Category = _allCategories[categoryIndex]; _allProducts.Add(product); } } //简单的分页 public ActionResult Index(int? page = 1, int? size = 10) { _currentPage = page.HasValue ? page.Value : _currentPage; _pageSize = size.HasValue ? size.Value : _pageSize; var model = _allProducts.ToPagedList(_currentPage, _pageSize); return View(model); } //根据产品分类搜索分页 public ActionResult PagingByCategory(string categoryName, int? page = 1, int? size = 10) { _currentPage = page.HasValue ? page.Value : _currentPage; _pageSize = size.HasValue ? size.Value : _pageSize; categoryName = categoryName ?? _allCategories[0]; var model = _allProducts.Where(m => m.Category == categoryName) .ToPagedList(_currentPage, _pageSize); ViewBag.CategoryName = new SelectList(_allCategories, categoryName); ViewBag.CategoryDisplayName = categoryName; return View(model); } //根据多个产品分类搜索分页 public ActionResult PagingByCategories(string[] categories, int? page = 1, int? size = 10) { _currentPage = page.HasValue ? page.Value : _currentPage; _pageSize = size.HasValue ? size.Value : _pageSize; categories = categories ?? new string[0]; var model = _allProducts.Where(m => categories.Contains(m.Category)) .ToPagedList(_currentPage, _pageSize); ViewBag.AllCategories = _allCategories; ViewBag.SelectedCategories = categories; return View(model); } //使用路由名称分页 public ActionResult PagingByRoute() { return View(); } //使用路由名称分页，为了模拟这种特殊的需求，所以使用了特殊的方式 public ActionResult ShowPagingByRoute(int? page = 1, int? size = 10) { _currentPage = page.HasValue ? page.Value : _currentPage; _pageSize = size.HasValue ? size.Value : _pageSize; var model = _allProducts.ToPagedList(_currentPage, _pageSize); return PartialView("_PartialPagingByRoute", model); } //ajax分页 public ActionResult Ajax() { return View(); } //ajax分页 public ActionResult AjaxPage(int? page = 1, int? size = 10) { _currentPage = page.HasValue ? page.Value : _currentPage; _pageSize = size.HasValue ? size.Value : _pageSize; var model = _allProducts.ToPagedList(_currentPage, _pageSize); return PartialView("_ProductGrid", model); } //自定义模版 public ActionResult Bootstrap(int? page = 1, int? size = 10) { _currentPage = page.HasValue ? page.Value : _currentPage; _pageSize = size.HasValue ? size.Value : _pageSize; var model = _allProducts.ToPagedList(_currentPage, _pageSize); return View(model); } //自定义页码路由键值对 public ActionResult CustomPageRouteValueKey(SearchModel search) { if (search.Page != null) _currentPage = (int)search.Page; var model = _allProducts.ToPagedList(_currentPage, _pageSize); return View(model); } }}
