本人ASP.net初学，网上找了一些分页的资料，看到这篇文章，没看到作者在名字，我转了你的文章，只为我可以用的时候方便查看，2010的文章了，不知道这技术是否过期。

以下才是正文

通常分页有3种方法，分别是asp.net自带的数据显示空间如GridView等自带的分页，第三方分页控件如aspnetpager，存储过程分页等。这里分别做总结。

第一种：使用GridView自带分页，这种是最简单的分页方法。
前台的方法：

后台方法：
代码

 
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

第二种：使用个性化显示的AspNetPager.dll进行分页
此处需要添加aspnetpager.dll的引用
前台：

后台：

 
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(); 
} 
} 
}

第三种：使用AspNetPager结合存储过程进行分页
这种方法分页稍微复杂一些，但是可以应付比较大的数据量。
前台:

 
"GridView1" runat="server" CssClass="GridTable" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" > 
 
"AspNetPager1" runat="server" 
CustomInfoHTML="第%CurrentPageIndex%页，共%PageCount%页，每页%PageSize%条" 
FirstPageText="首页" LastPageText="尾页" LayoutType="Table" NextPageText="下一页" 
onpagechanged="AspNetPager1_PageChanged" PageIndexBoxType="DropDownList" 
PagingButtonLayoutType="Span" PrevPageText="上一页" ShowCustomInfoSection="Left" 
ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="页" 
TextBeforePageIndexBox="转到">

后台：

 
//绑定方法中需要传递aspnetpager的两个属性 
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);//注意最后两个参数是aspnetpager的属性。 
this.GridView1.DataSource = ds; 
this.GridView1.DataBind(); 
} 
//分页控件的页索引变化事件 
protected void AspNetPager1_PageChanged(object src, EventArgs e) 
{ 
BindDetailReportToGv(); 
} 
//page_base中需要加载首次的数据条数 
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();

这里用的存储过程比较复杂，因为SQL语句没有能够放到视图中，也无法直接从表中查出结果，这个存储过程有点变态，如果有朋友看到了，希望能指点一下。
其实存储过程的核心在于：

 
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

代码

 
--下方可以忽略 
--我用到的是存储过程： 
set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
go 
create PROCEDURE [dbo].[pro_pager] 
(@startIndex INT, 
@endindex INT, 
@strwhere varchar(200) 
) 
AS
