| 标题 | ASP.NET存储过程实现分页效果(三层架构) |
| 范文 | 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 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。 |
