ASP.NET存储过程实现分页效果(三层架构)

框架  /  管理员 发布于 1年前   120

本文实例为大家分享了ASP.NET存储过程实现分页的具体代码，供大家参考，具体内容如下

实现效果：
文本框内输入跳转的页数，点击GO会跳转到该页

首先在项目下加入BLL,DAL,DataAccess,MODEL类库
1、前台界面

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="原始刷新分页.aspx.cs" Inherits="分页.原始刷新分页" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <script src="//article/js/Jquery1.7.js" type="text/javascript"></script> <script type="text/javascript">  $(function () {   $('#txtPageindex').focus(function () {    $(this).val("");   })  }) </script></head><body> <form id="form1" runat="server"> <div>  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">   <Columns>    <asp:BoundField DataField="Id" HeaderText="编号" />    <asp:BoundField DataField="NewsTitle" HeaderText="新闻标题" />    <asp:BoundField DataField="NewsContent" HeaderText="新闻内容" />    <asp:BoundField DataField="CreateTime"      DataFormatString="{0:yyyy-MM-dd hh:mm:ss}" HeaderText="创建时间" />   </Columns>  </asp:GridView> </div> <div>   <asp:LinkButton ID="btnFirst" runat="server" onclick="btnFirst_Click">第一页</asp:LinkButton>  <asp:LinkButton   ID="btnPre" runat="server" onclick="btnPre_Click">上一页</asp:LinkButton>  <asp:LinkButton ID="btnNext"    runat="server" onclick="btnNext_Click">下一页</asp:LinkButton>  <asp:LinkButton ID="btnLast" runat="server" onclick="btnLast_Click">最后一页</asp:LinkButton><asp:TextBox     ID="txtPageindex" runat="server"></asp:TextBox>  <asp:LinkButton ID="LinkButton5" runat="server" onclick="LinkButton5_Click">Go</asp:LinkButton> </div> </form></body></html>

2、后台代码

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.Data;namespace 分页{ public partial class 原始刷新分页 : System.Web.UI.Page {  int pagesize = 10;  protected void Page_Load(object sender, EventArgs e)  {      if (!IsPostBack)   {    ViewState["pageindex"] = 1;    GetLastPageindex();    LoadData();   }  }  private void GetLastPageindex()  {   BLL.T_News1 bnews = new BLL.T_News1();   int totalcount = bnews.GetRecordCount("");   if (totalcount % pagesize == 0)   {    ViewState["lastpageindex"] = totalcount / pagesize;   }   else { ViewState["lastpageindex"] = totalcount / pagesize+1; }    }  private void LoadData()  {   BLL.T_News1 bnews = new BLL.T_News1();   DataTable dt = bnews.GetListDataTable(pagesize,Convert.ToInt32(ViewState["pageindex"]));   this.GridView1.DataSource = dt;   this.GridView1.DataBind();      }  protected void btnFirst_Click(object sender, EventArgs e)  {   ViewState["pageindex"] = 1;   LoadData();  }  protected void btnPre_Click(object sender, EventArgs e)  {   int pageindex = Convert.ToInt32(ViewState["pageindex"]);   if (pageindex > 1)   {    pageindex--;    ViewState["pageindex"] = pageindex;    LoadData();   }  }  protected void btnNext_Click(object sender, EventArgs e)  {   int pageindex = Convert.ToInt32(ViewState["pageindex"]);   if (pageindex < Convert.ToInt32(ViewState["lastpageindex"]))   {    pageindex++;    ViewState["pageindex"] = pageindex;    LoadData();   }  }  protected void btnLast_Click(object sender, EventArgs e)  {    ViewState["pageindex"] = ViewState["lastpageindex"];   LoadData();  }    protected void LinkButton5_Click(object sender, EventArgs e)  {   int result;   if (int.TryParse(txtPageindex.Text, out result) == true)   {    ViewState["pageindex"] = txtPageindex.Text.Trim();    LoadData();   }   else { txtPageindex.Text = "请输入合法的数字"; }  } }}

3、数据库存储过程

declare @pagesize int;declare @pageindex int;SELECT * FROM (select ROW_NUMBER() over(order by Id) as rownumber,* from T_News1)TWHERE rownumber>(@pageindex-1)*@pagesize AND rownumber<=@pagesize*@pageindexGO CREATE PROC pro_fenye@pagesize int,@pageindex intasselect * from(select ROW_NUMBER() over(order by Id) as rownumber,* from T_News1)T WHERE rownumber>(@pageindex-1)*@pagesize AND rownumber<=@pageindex*@pagesizeGOexec pro_fenye 2,5

以上就是本文的全部内容，希望对大家的学习有所帮助。
