用aspnetpager实现datalist分页

微软的Datalist在做电子相册时候必不可少，但是不支持分页功能，都出到2008了还是没有分页功能，幸好网上有个专业的分页空间aspnetpager,帮我们解决了大问题，说实在话的，网上关于datalist分页的办法很多，但是我觉得都不是很简单实用，有的是url提交，有的是存储过程分页，一个字不方便。下面就是aspnetpager的分页，代码。

1.首先下载aspnetpager控件，http://www.webdiyer.com/download/default.aspx。

2.在工具箱里面添加aspnetpager控件。

3.前台引用

 

 

   < asp:DataList runat = " server "  ID = " dlPicList "  Width = " 100% "  Border = " 0 "  CellSpacing = " 0 "  CellPadding = " 0 "   RepeatColumns = " 4 "  RepeatDirection = " Horizontal " >
     < ItemTemplate >
        < a href = ' <%# "PicView.aspx?PicID="+Eval("PicID")%> ' >< asp:Image ID = " imPic "  runat = " server "  ImageUrl = ' <%# Bind("PicUrl")%> '  width = " 104 "  height = " 76 "  BorderWidth = " 1 "   />< br  />
                           < asp:Label runat = " server "  ID = " lblTitle "   Text = ' <%# Bind("DisTitle")%> ' ></ asp:Label ></ a >
     </ ItemTemplate >
     < ItemStyle CssClass = " word_green "  HorizontalAlign = " Center "   />
     </ asp:DataList >
   
< webdiyer:AspNetPager ID = " AspNetPager1 "  runat = " server "    PageSize = " 5 "   ShowBoxThreshold = " 1 "  AlwaysShow = " True "  FirstPageText = " 首页 "  LastPageText = " 末页 "
NextPageText = " 下一页 "  PrevPageText = " 上一页 "   onpagechanging = " AspNetPager1_PageChanging " >
   </ webdiyer:AspNetPager >

 

 

 4.后台代码

 

 

protected   void  Page_Load( object  sender, EventArgs e)
         {
            if (!IsPostBack)
            {
                BindData();
            }
        }

         private   void  BindData()
         {
         
            conn = ConfigurationManager.ConnectionStrings["STRING_SqlConn"].ToString();
            object[] para = { 0, picid };
            DataTable dt = DataOperator.TableUseTrans(conn, "SP_Pic_GetView", para);
            DataView dv = dt.DefaultView;
            //对用于分页的类的引用
            PagedDataSource pds = new PagedDataSource();
            pds.DataSource = dv;//设置数据源(DataTable类型)
            pds.AllowPaging = true;
            //每页显示的行数
            //pds.PageSize = 12;
            
          
            AspNetPager1.RecordCount = dv.Count;
            pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;
            pds.PageSize = AspNetPager1.PageSize;
            dlPicList.DataSource= pds;
            dlPicList.DataBind();
            

        }

         protected   void  AspNetPager1_PageChanging( object  src, Wuqi.Webdiyer.PageChangingEventArgs e)
         {
            AspNetPager1.CurrentPageIndex = e.NewPageIndex;
            BindData();
        }
