• asp.net 分页-利用后台直接生成html分页


    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++)
