使用说明

在页面的Page_Load方法体里输入以下属性
PageConten1.rows = 368; //总行数
            PageConten1.page_rows = 10; //每页分多少行
            PageConten1.page_info = 10; //每页要显示多少页码出来
            PageConten1.isRequest = 1; //是否带url参数，1为带，2为不带
            if (PageConten1.isRequest == 1)
            {
                index_page = int.Parse(Request["page"] == null ? ("1" + Request["page"]) : Request["page"]);
                PageConten1.pageName = "Test_4";
            }
            else
            {
                index_page = int.Parse(Request["hidSub"] == null ? ("1" + Request["hidSub"]) : Request["hidSub"]);
