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。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：

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：

<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();  

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

--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
