Asp.Net中的三种分页方式
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。
第一种：使用GridView自带分页，最简单的分页方法。
前台：
<asp:GridView ID="GridView1" AllowPaging="true" runat="server"
onpageindexchanging="GridView1_PageIndexChanging" PageSize="3">
</asp:GridView>
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());
}
this.GridView1.DataSource = dt;
this.GridView1.DataBind();
}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
this.GridView1.PageIndex = e.NewPageIndex;
BindData();
}
}
}
第二种：使用个性化显示的AspNetPager.dll进行分页
需要添加aspnetpager.dll的引用
前台：
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" >
</asp:GridView>
<webdiyer:AspNetPager ID="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"
onpagechanging="AspNetPager1_PageChanging" PageIndexBoxType="DropDownList"
PagingButtonLayoutType="Span" PrevPageText="上一页" ShowCustomInfoSection="Left"
ShowPageIndexBox="Always" SubmitButtonText="Go" PageSize="4" TextAfterPageIndexBox="页"
TextBeforePageIndexBox="转到">
</webdiyer:AspNetPager>
</div>
</form>
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：
<asp:GridView ID="GridView1" runat="server" CssClass="GridTable" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" >
</asp:GridView>
<webdiyer:AspNetPager ID="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">
</webdiyer:AspNetPager>
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();
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
--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
