The easy-to-use ASP. NET paging class is simple and easy to use.

It is useful when JavaScript UI controls are not used for websites

Usage:

Var ps = new PageString ();/* optional parameter */ps. setIsEnglish = true; // whether it is English (default: false) ps. setIsShowText = true; // whether to display paging text (default: true) // ps. textFormat = "" (default value: "span class = \" pagetext \ "strong" Total "/strong": {0} "strong" current "/strong": {1}/{2}/span) // ps. setPageIndexName Request ["pageIndex"] (default value: "pageIndex") ps. setIsAjax = false; // (default value: "false")/* function parameter */int total = 10000; int pageSize = 10; int pageIndex = Convert . ToInt32 (Request ["pageIndex"]); var page = ps. ToString (total, pageSize, pageIndex, "/UI/PageStringTest. aspx? "); // Get the page html OUTPUT Response. Write (page );
