Base Type Extensions
Microsoft AJAX Library erweitert JavaScript
Array - add, addRange, contains, insert, etc.Boolean - parseDate - format, parselocale, parseInvariant, etc.Error - argumentOutOfRange, etc.Number - format, parseLocale, parseInvariantObject - getType, getTypeNameString - format, endsWith, startWith, trim, etc.
$get, $find & $create …
Globale FunktionenVerweise auf statische Klassen
$get -> Sys.UI.DomElement.getElementById$create -> Sys.Component.create$find -> Sys.Application.findComponent$addHandler ->
Sys.UI.DomEvent.addHandler$removeHandler -> System.UI.DomEvent.removeHandler$clearHandlers -> Sys.UI.DomEvent.clearHandlers
Javascript Webservices
JSON statt XMLCa. 30% weniger OverheadNeues [ScriptService] Attribut
Automatische GenerierungWebservices BridgeAlternative: PageMethod
