通过aspnetpager为DataList分页

     今天整了半天才把DataList的分页搞定，下面把我的设计过程给大家讲讲：

      前台代码：

 

代码

< div  id ="newslistdiv" >
         < asp:DataList  ID ="NewsList"  runat ="server"  Width ="820px" >
             < HeaderTemplate >
                 < div >
                     < img  src ="../loginimages/newslisthead.gif"  alt =""   /></ div >
             </ HeaderTemplate >
             < ItemTemplate >
                 < dl >
                     < dd >
                        · < a  href ="#"  class ="rlk"  onclick ='window.location.href="DetailNews.aspx?ID=<%#Eval("NewsID")  % > "'> <% # Eval ( " NewsTitle " )  %> </ a >
                         &nbsp;&nbsp;&nbsp; <% # Eval ( " NewsTime " ,  " {0:yyyy-MM-dd} " ) %> < br  />
                     </ dd >
                 </ dl >
             </ ItemTemplate >
         </ asp:DataList >
     </ div >
     < div  style ="margin-bottom: 2px;"  align ="center" >
         < webdiyer:AspNetPager  ID ="AspNetPager1"  runat ="server"  PageSize ="15"  FirstPageText =" 首页 "
            LastPageText =" 尾页 "  NextPageText =" 下一页 "  OnPageChanged ="AspNetPager1_PageChanged"
            PrevPageText =" 上一页 "  Width ="100%"  AlwaysShow ="true"  CssClass ="anpager" >
         </ webdiyer:AspNetPager >
     </ div >

 

      后台代码：

 

代码

protected   void  Page_Load( object  sender, EventArgs e)
        {
             if  ( ! IsPostBack)
            {
                BindNewsDatalist();
            }
        }
        //绑定DataList的数据源
         private   void  BindNewsDatalist()
        {
            FJDWS.BusinessLogic.LNewsManager lnewsmanager  =   new  FJDWS.BusinessLogic.LNewsManager();

             this .AspNetPager1.RecordCount  =  lnewsmanager.FindAll().Count;
            PagedDataSource pds  =   new  PagedDataSource();     // 定义一个PagedDataSource类来执行分页功能
            pds.DataSource  =  lnewsmanager.FindAll();
            pds.AllowPaging  =   true ;
            pds.CurrentPageIndex  =  AspNetPager1.CurrentPageIndex  -   1 ;
            pds.PageSize  =  AspNetPager1.PageSize;

             this .NewsList.DataSource  =  pds;
            NewsList.DataBind();
        }

         protected   void  AspNetPager1_PageChanged( object  src, EventArgs e)
        {
             // AspNetPager1.CurrentPageIndex = e.NewPageIndex;
            BindNewsDatalist();
        }
