pager?是什么控件，我怎么没用过

Answer 3

  参考吴旗娃的分页控件，或 PageDataSource   用法

Answer 4

asp.net分页控件多好用啊，样式应该可以把，不过我没有试过。或者用C#自己写一个分页程序，那么样式可以自己做主了

随便写了个呵呵 抛砖引玉
                PagedDataSource ps = new PagedDataSource();
                ps.DataSource = dt.DefaultView;
                ps.AllowPaging = true;
                ps.PageSize = 10;
                int pagecount;
                if (Request.QueryString["page"] != null)
                    pagecount = Convert.ToInt32(Request.QueryString["page"].ToString());
                else
                    pagecount = 1;                ps.CurrentPageIndex = pagecount - 1;                                
                lblPagecount.Text = ps.PageCount.ToString();                
                
                lblList.Text = "";
                
                int MinPage = pagecount - 5;
                int MaxPage = pagecount + 5;
                if(MaxPage>ps.PageCount)
                    MaxPage=ps.PageCount;
                if (MinPage < 0)
                    MinPage = 0;               
                for (int i = MinPage; i < MaxPage; i++)
                {                        string url = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(i+1);                        string pg = Convert.ToString(i + 1);
                        if (i == pagecount-1)
                            pg = "<Font color=red>" + pg + "</font>";
                        lblList.Text += "<a href=" + url + " >[ " + pg + " ]</a>  ";                }                lblList.Text += "...";                    //Response.Write(ts.Rows[0][0]);
                    if (!ps.IsFirstPage)
                        this.hplFist.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(1);                if (!ps.IsFirstPage)
                    this.hplPrv.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(pagecount - 1);                if (!ps.IsLastPage)
                    this.hplNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(pagecount + 1);                if (!ps.IsLastPage)
                    this.hplLast.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(ps.PageCount);
                rep_Userans.DataSource = ps;
                rep_Userans.DataBind();

你直接用for循环把页码输出即可，最多就加上一些限制显示的页码数的判断，比如不能让上一页的页码小于1，也不能让下一页的页码大于总页数等
