關於翻頁一直很讓我撓頭，今天總結乙個比較經典的。
1.pagecontrol.ascx

}3.呼叫的地方：test.aspx
先註冊，再呼叫：
<%@ register src="~/pagecontrol.ascx" tagprefix="page" tagname="pagercontrol" %>
4.test.aspx.cs
// 翻頁初始化
this.page1.currentpage = 0;
this.page1.totalrecordcount = 0;
this.page1.recordperpage = 10;
this.page1.paint();
usermanagement usermanagement = new usermanagement ();
list = usermanagement .getinfobyuserid(
this.page1.recordperpage,
this.page1.currentpage,
ref total,
(string)viewstate["status"],
userid);
this.page1.totalrecordcount = total;
this.page1.paint();
5.後台的儲存過程:sp_getuserinfo
create proc [dbo].[sp1_online_getorderinfo](
@pagesize int,
@currpage int,
@total int output,
@status nvarchar(1),
@userid int)as
set lock_timeout 1000
declare @retcode int
select @total = count(1)
from table1 as o with(nolock)
where
(@status is null or o.status = @status )
and o.userid = @userid
select
a,b,
c,rowno
from
(select
o.a,
i.b,
d.c,
row_number()over(
order by o.id desc
) as rowno
from table1 as o with(nolock)
inner join table2 as i with(nolock) on i.id= o.id
inner join table3 as d with(nolock) on d.id= o.id
where
(@status is null or o.status = @status)
and o.userid = @userid
) t1
where t1.rowno - 1 >= (@currpage*@pagesize)
and t1.rowno - 1 < ((@currpage+1)*@pagesize)
order by t1.rowno
6.呼叫儲存過程的檔案（資料層）userdb.cs
internal listgetinfobyuserid(
int pagesize,
int currpage,
ref int total,
string status,
int userid)
internal static listgetlistfromdataset(dataset dataset)
return retlist;
}else
}7.業務層畫面
public listgetinfobyuserid(
int pagesize,
int currpage,
ref int total,
string status,
int userid)
{userdb userdb = new userdb();
return userdb.getinfobyuserid(pagesize, currpage, ref total, status, userid);
