Asp.Net中的三种分页方式总结

解决分页这个问题搞了一天半，耗时巨大，现在总结一下。

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：

<asp:GridView ID="GridView1" AllowPaging="true" runat="server"
onpageindexchanging="GridView1_PageIndexChanging" PageSize="3">
</asp:GridView>

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 < 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

此处需要添加aspnetpager.dll的引用

前台：

代码

后台：

代码

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:

代码

<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：

代码

//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：

代码

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
