扩展程序使您能够自定义和扩展ASP的功能. NET控件，而无需创建新类.
没有日历扩展器，而是Ajaxtoolkit的日历是一种文本框扩展器，其中文本框具有日历的其他行为.

标准日历控件是具有定义行为的单个控件. AjaxToolkit的Calendar是一个文本框控件，扩展到一个具有给定行为的级别(可用于通过claendar选择日期).


请参阅: ^ ]

Extenders enable you to customize and extend the capabilities of ASP.NET controls without having to create new classes.
There is no calendar extender, instead a calendar of Ajaxtoolkit is a kind of textbox extender where textbox has additional behaviour of calendar.

Standard calendar control is a one single control having a defined behaviour. Calendar of AjaxToolkit is a textbox control extended to a level(with a given behaviour) that can be used for picking dates via claendar.
