详解一个ASP.NET MVC分页效果
在这里我们将谈到的是ASP.NET MVC框架中的一个HTML辅助类，希望通过本文能对大家了解ASP.NET MVC分页有所帮助。
#T#
本人写的一个ASP.NET MVC分页Helper，支持普通分页（也就是，首页、上一页、下一页、末页等），综合分页（普通分页和数字分页的综合）。下面是ASP.NET MVC分页效果：
分页代码：

202 PagerQuery.cs包含两个属性，一个是PageInfo实体类属性
Pager，包含RecordCount，CurrentPageIndex，PageSize三个属性。一个是Model EntityList属性。
代码
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Web;
- namespace System.Web.Mvc
- {
- public class PagerQuery<TPager,TEntityList>
- {
- public PagerQuery(TPager pager, TEntityList entityList)
- {
- this.Pager = pager;
- this.EntityList = entityList;
- }
- public TPager Pager { get; set; }
- public TEntityList EntityList { get; set; }
- }
- }
PageInfo.cs
代码
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Web;
- namespace System.Web.Mvc
- {
- public class PagerInfo
- {
- public int RecordCount { get; set; }
- public int CurrentPageIndex { get; set; }
- public int PageSize { get; set; }
- }
- }
使用示例：
代码
- <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master"
- Inherits="System.Web.Mvc.ViewPage<PagerQuery<PagerInfo, IList<NewsArticleInfo>>>" %>
- <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
- NewsList
- </asp:Content>
- <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
- <h2>NewsList</h2>
- <table> <tr> <th></th>
- <th>NoteID</th>
- <th>Title</th>
- <th>Author</th>
- <th>Hit</th>
- <th>ReplyNum</th>
- </tr>
- <% foreach (var item in Model.EntityList) { %>
- <tr><td>
- <%= Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) %> |
- <%= Html.ActionLink("Details", "NewsDetail", new { noteID=item.NoteID })%>
- </td><td>
- <%= Html.Encode(item.NoteID) %>
- </td>
- <td><%= Html.Encode(item.Title) %></td>
- <td><%= Html.Encode(item.Author)%></td>
- <td><%= Html.Encode(item.Hit)%></td>
- <td><%= Html.Encode(item.ReplyNum)%></td>
- </tr>
- <% } %></table>
- <p>
- <%=Html.Pager("pager",Model.Pager.CurrentPageIndex,Model.Pager.PageSize,Model.Pager.RecordCount,PageMode.Numeric) %></p>
- </asp:Content>
controler：
- [AcceptVerbs(HttpVerbs.Get)]
- ublic ActionResult NewsList(int boardID,int? page)
- {
- PagerInfo pager = new PagerInfo();
- NewsArticleInfo info = new NewsArticleInfo();
- info.NewsBoard = new NewsBoardInfo();
- info.NewsBoard.BoardID = boardID;
- pager.RecordCount = Resolve ().GetArticleDataList(info, ArticleTypeEnum.Pass);
- pager.PageSize = 10;
- pager.CurrentPageIndex = (page!=null?(int)page:1);
- IList result = Resolve ().GetArticleDataList(pager.CurrentPageIndex, pager.PageSize, ArticleTypeEnum.Pass, info);
- PagerQuery> query = new PagerQuery>(pager,result);
- return View(query);
