本人ASP.net初學，網上找了一些分頁的資料，看到這篇文章，沒看到作者在名字，我轉了你的文章，只為我可以用的時候方便查看，2010的文章了，不知道這技術是否過期。
以下才是正文
通常分頁有3種方法，分別是asp.net自帶的數據顯示空間如GridView等自帶的分頁，第三方分頁控件如aspnetpager，存儲過程分頁等。這裏分別做總結。
第一種：使用GridView自帶分頁，這種是最簡單的分頁方法。
前臺的方法：
<asp:GridView ID="GridView1" AllowPaging="true" runat="server" onpageindexchanging="GridView1_PageIndexChanging" PageSize="3"> </asp:GridView>
後臺方法：
代碼
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using JXSoft.TicketManage.Model;
using JXSoft.TicketManage.BLL;
using System.Text.RegularExpressions;
using System.Data;
namespace JXSoft.TicketManage.Web
{
public partial class Test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindData();
}
}
protected void BindData()
{
DataTable dt=new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
for (int i = 0; i < 10;i++ )
{
dt.Rows.Add(i.ToString(), i.ToString());
}
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
this.GridView1.PageIndex = e.NewPageIndex;
BindData();
}
}
}
第二種：使用個性化顯示的AspNetPager.dll進行分頁
此處需要添加aspnetpager.dll的引用
前臺：
<form id="form1" runat="server"> <div> <asp:GridView ID="GridView1" runat="server" > </asp:GridView> <webdiyer:AspNetPager ID="AspNetPager1" runat="server" CustomInfoHTML="第%CurrentPageIndex%頁，共%PageCount%頁，每頁%PageSize%條" FirstPageText="首頁" LastPageText="尾頁" LayoutType="Table" NextPageText="下一頁" onpagechanging="AspNetPager1_PageChanging" PageIndexBoxType="DropDownList" PagingButtonLayoutType="Span" PrevPageText="上一頁" ShowCustomInfoSection="Left" ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="頁" TextBeforePageIndexBox="轉到"> </webdiyer:AspNetPager> </div> </form>
後臺：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using JXSoft.TicketManage.Model; using JXSoft.TicketManage.BLL; using System.Text.RegularExpressions; using System.Data; namespace JXSoft.TicketManage.Web { public partial class Test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { BindData(); } } protected void BindData() { DataTable dt=new DataTable(); dt.Columns.Add("ID"); dt.Columns.Add("Name"); for (int i = 0; i < 10;i++ ) { dt.Rows.Add(i.ToString(), i.ToString()); } DataSet ds = new DataSet(); ds.Tables.Add(dt); Pager(this.GridView1, this.AspNetPager1, ds); } protected void Pager(GridView dl, Wuqi.Webdiyer.AspNetPager anp, System.Data.DataSet dst) { PagedDataSource pds = new PagedDataSource(); pds.DataSource = dst.Tables[0].DefaultView; pds.AllowPaging = true; anp.RecordCount = dst.Tables[0].DefaultView.Count; pds.CurrentPageIndex = anp.CurrentPageIndex - 1; pds.PageSize = anp.PageSize; dl.DataSource = pds; dl.DataBind(); } protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e) { AspNetPager1.CurrentPageIndex = e.NewPageIndex; BindData(); } } }
第三種：使用AspNetPager結合存儲過程進行分頁
這種方法分頁稍微復雜一些，但是可以應付比較大的數據量。
前臺:
<asp:GridView ID="GridView1" runat="server" CssClass="GridTable" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" > </asp:GridView> <webdiyer:AspNetPager ID="AspNetPager1" runat="server" CustomInfoHTML="第%CurrentPageIndex%頁，共%PageCount%頁，每頁%PageSize%條" FirstPageText="首頁" LastPageText="尾頁" LayoutType="Table" NextPageText="下一頁" onpagechanged="AspNetPager1_PageChanged" PageIndexBoxType="DropDownList" PagingButtonLayoutType="Span" PrevPageText="上一頁" ShowCustomInfoSection="Left" ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="頁" TextBeforePageIndexBox="轉到"> </webdiyer:AspNetPager>
後臺：
//綁定方法中需要傳遞aspnetpager的兩個屬性 protected void DataBind(){ DataSet ds = reportQueryBLL.GetTcikDetailReport(this.txtStartDate.Text,this.txtEndDate.Text,int.Parse( this.DropDownListPartment1.SelectedValue), this.txtPayPerson1.Text,this.txtTicketNum.Text,this.txtTicketNo.Text, AspNetPager1.StartRecordIndex,AspNetPager1.EndRecordIndex);//註意最後兩個參數是aspnetpager的屬性。 this.GridView1.DataSource = ds; this.GridView1.DataBind(); } //分頁控件的頁索引變化事件 protected void AspNetPager1_PageChanged(object src, EventArgs e) { BindDetailReportToGv(); } //page_base中需要加載首次的數據條數 DataSet ds = reportQueryBLL.GetDetail(this.txtStartDate.Text, this.txtEndDate.Text, int.Parse(this.DropDownListPartment1.SelectedValue), this.txtPayPerson1.Text, this.txtTicketNum.Text, this.txtTicketNo.Text); this.AspNetPager1.RecordCount = ds.Tables[0].Rows.Count; BindDetailReportToGv();
這裏用的存儲過程比較復雜，因為SQL語句沒有能夠放到視圖中，也無法直接從表中查出結果，這個存儲過程有點變態，如果有朋友看到了，希望能指點一下。
其實存儲過程的核心在於：
Create PROCEDURE [dbo].[P_GetPagedOrders2005] (@startIndex INT, @endindex INT ) AS select * from (SELECT ROW_NUMBER() OVER(ORDER BY IPid DESC) AS rownum, [IPid],[IPFrom],[IPTo],[IPLocation],[IPCity],[IPToNumber],[IPFromNumber] from IPInfo) as U WHERE rownum between @startIndex and @endIndex GO
代碼
--下方可以忽略 --我用到的是存儲過程： set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go create PROCEDURE [dbo].[pro_pager] (@startIndex INT, @endindex INT, @strwhere varchar(200) ) AS SELECT tb_On_Tick_Info.On_Tick_ID_Int,tb_On_Tick_Info.On_Tick_SellDatetime_Dtm,tb_On_Tick_Info.On_Tick_TicketsNum_Str, tb_Department_Info.Dept_Name_Str, tb_User_Info.User_Name_Str, tb_On_Tick_Info.On_Tick_SellNumber_Str, tb_On_Tick_Info.On_Tick_ShouldPay_Dec, tb_On_Tick_Info.On_Tick_Count_Int, tb_On_Tick_Info.On_Tick_Discount_Dec, tb_On_Tick_Details.On_Tick_Details_StartNo_Int, CHARINDEX(N‘a‘, tb_On_Tick_Info.On_Tick_Note_Text) AS Expr3, tb_User_Info_1.User_Name_Str AS Expr1, tb_Ticket_Type.TicketType_Name_Dec, COUNT( tb_On_Tick_Details.On_Tick_Details_ID_Int) AS Expr2 ,tb_Department_Info.Dept_ID_Int into #temp FROM tb_User_Info INNER JOIN tb_On_Tick_Info ON tb_User_Info.User_ID_Int = tb_On_Tick_Info.On_Tick_SellPerson_Int INNER JOIN tb_Department_Info ON tb_User_Info.User_DepartID_Int = tb_Department_Info.Dept_ID_Int INNER JOIN tb_User_Info AS tb_User_Info_1 ON tb_On_Tick_Info.On_Tick_PayPerson_Int = tb_User_Info_1.User_ID_Int INNER JOIN tb_On_Tick_Details ON tb_On_Tick_Info.On_Tick_SellNumber_Str = tb_On_Tick_Details.On_Tick_SellNumber_Str INNER JOIN tb_Ticket_Type ON tb_On_Tick_Details.On_Tick_Details_TicketsType_Int = tb_Ticket_Type.TicketType_ID_Int where 1=1 +@strwhere GROUP BY tb_On_Tick_Info.On_Tick_SellDatetime_Dtm,tb_On_Tick_Info.On_Tick_TicketsNum_Str, tb_Department_Info.Dept_Name_Str, tb_User_Info.User_Name_Str, tb_On_Tick_Info.On_Tick_SellNumber_Str, tb_On_Tick_Info.On_Tick_ShouldPay_Dec, tb_On_Tick_Info.On_Tick_Count_Int, tb_On_Tick_Info.On_Tick_Discount_Dec, CHARINDEX(N‘a‘, tb_On_Tick_Info.On_Tick_Note_Text), tb_User_Info_1.User_Name_Str, tb_Ticket_Type.TicketType_Name_Dec, tb_On_Tick_Details.On_Tick_Details_StartNo_Int ,tb_Department_Info.Dept_ID_Int,tb_On_Tick_Info.On_Tick_ID_Int declare @sql varchar(8000) set @sql = ‘select CONVERT(varchar(12) , On_Tick_SellDatetime_Dtm, 111 ) as On_Tick_SellDatetime_Dtm,Dept_Name_Str,User_Name_Str,On_Tick_SellNumber_Str,convert(varchar(15), On_Tick_ShouldPay_Dec) as On_Tick_ShouldPay_Dec,On_Tick_Count_Int,On_Tick_Discount_Dec‘ select @[email protected]+‘,sum(case tickettype_name_dec when ‘‘‘+tickettype_name_dec+‘‘‘ then expr2 else 0 end) [‘+tickettype_name_dec+‘]‘ from (select distinct tickettype_name_dec from tb_Ticket_Type ) as a set @[email protected]+‘ ,expr3,Expr1,On_Tick_TicketsNum_Str,Dept_ID_Int,On_Tick_ID_Int into ##t from #temp group by On_Tick_SellDatetime_Dtm,Dept_Name_Str,On_Tick_TicketsNum_Str,User_Name_Str,On_Tick_SellNumber_Str,On_Tick_ShouldPay_Dec,On_Tick_Count_Int, On_Tick_Discount_Dec ,expr3,Expr1,Dept_ID_Int,On_Tick_ID_Int order by On_Tick_SellDatetime_Dtm ‘ exec( @sql ) --select * from ##t select * from (SELECT ROW_NUMBER() OVER(ORDER BY on_tick_id_int DESC) AS rownum, * from ##t) as U WHERE rownum between @startIndex and @endIndex drop table ##t
