asp.net数字分页效果

<div id="PageInfo" runat="server" class="paginator "><!--放在页面的DIV标签-->

<!--下面是分页的3种样式-->

 <style type="text/css">
        .paginator { font: 11px Arial, Helvetica, sans-serif;padding:10px 20px 10px 0; margin: 0px;}
        .paginator a {padding: 1px 6px; border: solid 1px #ddd; background: #fff; text-decoration: none;margin-right:2px}
        .paginator a:visited {padding: 1px 6px; border: solid 1px #ddd; background: #fff; text-decoration: none;}
        .paginator .cpb {padding: 1px 6px;font-weight: bold; font-size: 13px;border:none}
        .paginator a:hover {color: #fff; background: #ffa501;border-color:#ffa501;text-decoration: none;}

 <!--放在后台的绑定数据代码-->

 DataSet ds = new NewsFacade().GetAllData();
        InfoList.DataSource = ds.Tables[0].DefaultView;
        InfoList.DataBind();
        this.PageInfo.InnerHtml = PageNums.GetPageNum(ds, InfoList, 12); //传入DataSet,DataList名称和分页大小
