ASP.NET存儲過程實現(xiàn)分頁效果(三層架構(gòu))

字號:


    本文實例為大家分享了ASP.NET存儲過程實現(xiàn)分頁的具體代碼,供大家參考,具體內(nèi)容如下
    首先在項目下加入BLL,DAL,DataAccess,MODEL類庫
    1、前臺界面
    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="原始刷新分頁.aspx.cs" Inherits="分頁.原始刷新分頁" %>
    <!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="編號" />
        <asp:BoundField DataField="NewsTitle" HeaderText="新聞標題" />
        <asp:BoundField DataField="NewsContent" HeaderText="新聞內(nèi)容" />
        <asp:BoundField DataField="CreateTime"
         DataFormatString="{0:yyyy-MM-dd hh:mm:ss}" HeaderText="創(chuàng)建時間" />
       </Columns>
      </asp:GridView>
     </div>
     <div>
       <asp:LinkButton ID="btnFirst" runat="server" onclick="btnFirst_Click">第一頁</asp:LinkButton>
      <asp:LinkButton
       ID="btnPre" runat="server" onclick="btnPre_Click">上一頁</asp:LinkButton>
      <asp:LinkButton ID="btnNext"
        runat="server" onclick="btnNext_Click">下一頁</asp:LinkButton>
      <asp:LinkButton ID="btnLast" runat="server" onclick="btnLast_Click">最后一頁</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、后臺代碼
    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 分頁
    {
     public partial class 原始刷新分頁 : 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 = "請輸入合法的數(shù)字"; }
      }
     }
    }
    3、數(shù)據(jù)庫存儲過程
    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
