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

< 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：

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()); 
            } 
            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:

 

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
