Textformat= "" (Default: Span class= "Pagetext" "strong" in total "/strong": {0} article "strong" The current "/strong": {1}/{2} "/span")//ps. Setpageindexname request["PageIndex" (Default value: "PageIndex") Ps. Setisajax = false;//(default: "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"); Gets the page HTML output Response.Write (page);
