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" %>
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
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
