一直想做一个属于自己的分页, 1:我试过用datapage,虽然是很好用,但是必须要配合datalist才能使用,感觉不太好 2:自己写分页控件,目前正在摸索中,关键是怎么分页的问题,有的是用datatable传进去分页,感觉效率有点低 3:就是今天我使用的方法,存储过程+Div+css分页了 说明:本人是毕业半年的菜鸟,以下程序全是按照自己的想法来写的,原创勿喷,并请大神们给出指导,谢谢了。 1:建好存储过程 ALTER procedure [dbo].[p_news_query] @Page int as begin select top 5 new_id,new_title,new_url,new_content_text,create_time,user_name from (select *,ROW_NUMBER() over(order by new_id desc ) as RowNumber from (select new_id,new_title,new_url,new_content_text, dbo.f_ConvertDate(a.create_time) create_time, b.user_name from xs_new a left join xs_users b on b.user_no=a.create_user )TI ) A where A.RowNumber>(@Page-1)*5 end 目前实验的是每页5条数据,传入当前页码就可以了
2:前台定义一个div ,用于显示 <div id="divPage" runat="server" class="divpage"> </div>
3:后台根据传入参数来拼html 目前是模仿博客园的模式,前后显示5条,多余的加...后到最后一条 StringBuilder sbr = new StringBuilder(); int ITotalCount = pageLogic.QueryNewsCount(); int IPage = 1; if (Request["p"] != null) { IPage = Convert.ToInt32(Request["p"]); } int IPageCount = 5; int ITotalPage = ITotalCount / IPageCount; if (ITotalCount % IPageCount > 0) { ITotalPage += 1; } if (IPage != 1) { sbr.Append("<a href=\"news.aspx?p=" + (IPage - 1).ToString() + "\">上一页</a>"); } if (ITotalPage <= 10) { for (int i = 1; i <= ITotalPage; i++) { if (i == IPage) { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\" class=\"pageSelect\">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\">" + i.ToString() + "</a>"); } } } else { if (IPage - 5 > 2 && IPage + 7 < ITotalPage)//前后都有的 { sbr.Append("<a href=\"news.aspx?p=1\">1</a>..."); for (int i = IPage - 5; i <= IPage + 5; i++) { if (i == IPage) { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\" class=\"pageSelect\">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\">" + i.ToString() + "</a>"); } } sbr.Append("...<a href=\"news.aspx?p=" + ITotalPage.ToString() + "\">" + ITotalPage.ToString() + "</a>"); } else if (IPage - 5 <= 2)//前面不够,后面有多余 { for (int i = 1; i <= 10; i++) { if (i == IPage) { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\" class=\"pageSelect\">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\">" + i.ToString() + "</a>"); } } sbr.Append("...<a href=\"news.aspx?p=" + ITotalPage.ToString() + "\">" + ITotalPage.ToString() + "</a>"); } else if (IPage + 7 >= ITotalPage)//前面多余,后面不足 { sbr.Append("<a href=\"news.aspx?p=1\">1</a>..."); for (int i = ITotalPage - 10; i <= ITotalPage; i++) { if (i == IPage) { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\" class=\"pageSelect\">" + i.ToString() + "</a>"); } else { sbr.Append("<a href=\"news.aspx?p=" + i.ToString() + "\">" + i.ToString() + "</a>"); } } } } if (IPage != ITotalPage) { sbr.Append("<a href=\"news.aspx?p=" + (IPage + 1).ToString() + "\">下一页</a>"); } divPage.InnerHtml = sbr.ToString(); rptNews.DataSource = pageLogic.QueryNews(IPage); rptNews.DataBind();
