MVC分页之MvcPager使用详解

最近刚刚接触MVC不久，因项目中要用到分页，网上找了下资料，最后采用了MvcPager(http://www.webdiyer.com/),支持同步和Ajax异步分页。废话不多说了直接上代码。

一.MvcPager异步
ViewModel:

 public class Article
 {
 [Display(Name = "信息编号")]
 public int ID { get; set; }

 [Display(Name = "信息标题")]
 public string Title { get; set; }

 [Display(Name = "信息内容")]
 public string Content { get; set; }
 }

 public class AjaxPager
 {
 public PagedListArticle> Articles { get; set; } 
 }

Control:

/// summary>
 /// 异步分页测试
 /// /summary>
 /// param name="id">pageIndex/param>
 /// param name="key">关键字/param>
 /// returns>/returns>
 public ActionResult AjaxPaging(int? id = 1, string key = null)
 {
  int totalCount = 0;
  int pageIndex = id ?? 1;
  int pageSize = 2;
  ListArticle> infoList = new SoleFuDAL.MyTest().GetArticleList(key, pageSize, (pageIndex - 1) * 2, out totalCount);
  PagedListArticle> InfoPager = infoList.AsQueryable().OrderByDescending(o => o.ID).ToPagedList(pageIndex, pageSize);
  InfoPager.TotalItemCount = totalCount;
  InfoPager.CurrentPageIndex = (int)(id ?? 1);

  Models.MyTest.AjaxPager model = new Models.MyTest.AjaxPager();
  model.Articles = InfoPager;
  if (Request.IsAjaxRequest())
  {
  return PartialView("_ArticleList", model);
  }
  return View(model);
 }

View:

@model soulefu_manage.Models.MyTest.AjaxPager
@using Webdiyer.WebControls.Mvc;

!DOCTYPE html>

html>
head>
 meta name="viewport" content="width=device-width" />
 title>MVCPager-AjaxPaging/title>
 link href="~/Content/pagerstyles.css" rel="stylesheet" />
 link href="~/Content/bootstrap.css" rel="stylesheet" />
/head>
body>
 div style="padding: 15px;">
 @using (Html.BeginForm("AjaxPaging", "MyTest", new RouteValueDictionary { { "id", "" } }, FormMethod.Get))
 {
  @Html.Label("关键字：") input name="key" value="@Request.QueryString["key"]" />input type="submit" value="查询" />
 }

 @*分页Table*@
 @{ Html.RenderPartial("_ArticleTable"); }

 div class="text-center">
  @Ajax.Pager(Model.Articles, new PagerOptions
  {
  PageIndexParameterName = "id",
  FirstPageText = "首页",
  PrevPageText = "上一页",
  NextPageText = "下一页",
  LastPageText = "末页",
  NumericPagerItemCount = 5,
  ContainerTagName = "ul",
  CssClass = "pagination",
  CurrentPagerItemTemplate = "li class=\"active\">a href=\"#\">{0}/a>/li>",
  DisabledPagerItemTemplate = "li class=\"disabled\">a>{0}/a>/li>",
  PagerItemTemplate = "li>{0}/li>"
  }).AjaxOptions(a => a.SetUpdateTargetId("articles"))
 /div>
 /div>
/body>
/html>

@model soulefu_manage.Models.MyTest.AjaxPager

table class="table table-bordered table-striped">
 tr>
 th class="nowrap">序号/th>
 th>
  标题
 /th>
 th>
  内容
 /th>
 /tr>
 @foreach (var item in Model.Articles)
 {
 tr>
  td>@Html.DisplayFor(model => item.ID)/td>
  td>
  @Html.DisplayFor(modelItem => item.Title)
  /td>
  td>
  @Html.DisplayFor(modelItem => item.Content)
  /td>
 /tr>
 }
/table>

二.MvcPager同步
ViewModel（此处可不增加，直接和异步的共用同一个）:

 public class MVCPager
 {
 //信息列表
 public PagedListArticle> Articles { get; set; }
 }

Control:

 /// summary>
 /// 同步分页测试
 /// /summary>
 /// param name="id">pageIndex/param>
 /// param name="key">关键字/param>
 /// returns>/returns>
 public ActionResult MVCPager(int? id = 1, string key = null) 
 {
  int totalCount = 0;
  int pageIndex = id ?? 1;
  int pageSize = 2;
  ListArticle> infoList = new SoleFuDAL.MyTest().GetArticleList(key, pageSize, (pageIndex - 1) * 2, out totalCount);
  PagedListArticle> InfoPager = infoList.AsQueryable().OrderByDescending(o => o.ID).ToPagedList(pageIndex, pageSize);
  InfoPager.TotalItemCount = totalCount;
  InfoPager.CurrentPageIndex = (int)(id ?? 1);

  //数据组装到viewModel
  Models.MyTest.MVCPager model = new Models.MyTest.MVCPager();
  model.Articles = InfoPager;
  return View(model);
 }

View:

@model soulefu_manage.Models.MyTest.MVCPager
@using Webdiyer.WebControls.Mvc;

!DOCTYPE html>

html>
head>
 meta name="viewport" content="width=device-width" />
 title>MVCPager/title>
 link href="~/Content/pagerstyles.css" rel="stylesheet" />
 link href="~/Content/bootstrap.css" rel="stylesheet" />
/head>
body>
 div style="padding:15px;">
 @using (Html.BeginForm("MVCPager", "MyTest", new RouteValueDictionary { { "id", "" } }, FormMethod.Get))
 {
  @Html.Label("关键字：")input name="key" value="@Request.QueryString["key"]" />input type="submit" value="查询" />
 }

 table class="table table-bordered table-striped">
  tr>
  th>编号/th>
  th>标题/th>
  th>内容/th>
  /tr>
  @foreach (var info in Model.Articles)
  {
  tr>
   td>@Html.DisplayFor(model => info.ID)/td>
   td>@Html.DisplayFor(model => info.Title)/td>
   td>@Html.DisplayFor(model => info.Content)/td>
  /tr>
  }
 /table>

 div class="text-center">
  nav>
  @Html.Pager(Model.Articles, new PagerOptions
  {
   PageIndexParameterName = "id",
   FirstPageText = "首页",
   PrevPageText = "上一页",
   NextPageText = "下一页",
   LastPageText = "末页",
   ContainerTagName = "ul",
   CssClass = "pagination",
   CurrentPagerItemTemplate = "li class=\"active\">a href=\"#\">{0}/a>/li>",
   DisabledPagerItemTemplate = "li class=\"disabled\">a>{0}/a>/li>",
   PagerItemTemplate = "li>{0}/li>",
   Id = "bootstrappager"
  })
  /nav>
 /div>
 /div>
/body>
/html>

获取测试数据方法（共用）：

 public class MyTest
 {
 /// summary>
 /// 获取测试数据
 /// /summary>
 /// param name="key">/param>
 /// param name="PageSize">/param>
 /// param name="CurrentCount">/param>
 /// param name="TotalCount">/param>
 /// returns>/returns>
 public ListArticle> GetArticleList(string key, int PageSize, int CurrentCount, out int TotalCount)
 {
  string tabName = string.Format("Article");
  string strWhere = " 1=1";
  if (!string.IsNullOrEmpty(key))
  {
  //SQL关键字过滤 包含关键字则不拼接SQL
  if (!SqlInjection.GetString(key))
  {
   strWhere += string.Format(" AND (Title LIKE '%{0}%' OR Content LIKE '%{0}%')", key);
  }
  }
  string Order = string.Format("ID ASC");
  DataSet ds = SqlHelper.GetList(SqlHelper.connStr, Order, PageSize, CurrentCount, tabName, strWhere, out TotalCount);
  ListArticle> list = new ListArticle>();
  if (ds != null  ds.Tables.Count > 0)
  {
  foreach (DataRow dr in ds.Tables[0].Rows)
  {
   Article model = new Article();
   model.ID = Convert.ToInt32(dr["ID"]);
   model.Title = dr["Title"].ToString();
   model.Content = dr["Content"].ToString();
   list.Add(model);
  }
  }
  return list;
 }
 }
