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

ASP.NET存储过程实现分页效果(三层架构)

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="/UploadFiles/2021-04-02/Jquery1.7.js">

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。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
