点击刷新
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:Gridwww.cppcns.comView> </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="btnNwww.cppcns.comext_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:www.cppcns.comTextBox> <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; }
}
http://www.cppcns.com 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)
SERYTZjFf {
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。
