asp.net中使用repeater和PageDataSource搭配实现分页代码

 pageddatasource objpage = new pageddatasource();

            dataview dv = bllbook.getlistbystate("", true);
            //设置数据源
            objpage.datasource =dv ;

            //允许分页
            objpage.allowpaging = true;

            //设置每页显示的项数
            objpage.pagesize = 10;

            //定义变量用来保存当前页索引
            int curpage;
            int recordcount;
            int pagecount = objpage.pagecount;

            recordcount = dv.count;

            //判断是否具有页面跳转的请求
            if (request.querystring["page"] != null)
            {
                curpage = convert.toint32(request.querystring["page"]);
            }

            else
            {
                curpage = 1;
            }

            //设置当前页的索引
            objpage.currentpageindex = curpage - 1;

            //显示状态信息
            lblcurpage.text = "第  " + curpage.tostring() + "/" + pagecount.tostring() + "页    共  " + recordcount.tostring() + " 记录 ";

            //如果当前页面不是首页
            if (!objpage.isfirstpage)
            //定义 "上一页 "超级链接的url为：当前执行页面的虚拟路径,并传递下一页面的索引值
            {
                lnkprev.navigateurl = request.currentexecutionfilepath + "?page=" + convert.tostring(curpage - 1);
                lnkfirst.navigateurl = request.currentexecutionfilepath + "?page=" + convert.tostring(1);
            }

            //如果当前页面不是最后一页
            if (!objpage.islastpage)
            //定义 "下一页 "超级链接的url为：当前执行页面的虚拟路径,并传递下一页面的索引值
            {
                lnknext.navigateurl = request.currentexecutionfilepath + "?page=" + convert.tostring(curpage + 1);
                lnklast.navigateurl = request.currentexecutionfilepath + "?page=" + convert.tostring(pagecount);
            }

            //进行数据绑定
            repeater1.datasource = objpage;
            repeater1.databind();
