这里有新鲜出炉的精品教程,程序狗速度看过来!

ASP.NET

ASP.NET 是.NET FrameWork的一部分,是一项微软公司的技术,是一种使嵌入网页中的脚本可由因特网服务器执行的服务器端脚本技术,它可以在通过HTTP请求文档时再在Web服务器上动态创建它们。 指 Active Server Pages(动态服务器页面) ,运行于 IIS(Internet Information Server 服务,是Windows开发的Web服务器)之中的程序 。


这篇文章主要为大家详细介绍了ASP.NET存储过程实现分页,利用三层架构实现分页效果,有参考价值的一篇文章,感兴趣的小伙伴们可以参考一下

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="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)T
WHERE rownumber>(@pageindex-1)*@pagesize AND rownumber<=@pagesize*@pageindex

GO 
CREATE PROC pro_fenye
@pagesize int,
@pageindex int

as
select * from(select ROW_NUMBER() over(order by Id) as rownumber,* from T_News1)T 
WHERE rownumber>(@pageindex-1)*@pagesize AND rownumber<=@pageindex*@pagesize
GO
exec 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。
