Example of using ControlBase class

As I've learened from ASP.NET AJAX IN ACTION AJAX toolkit also allow as to create Script Controls (AJAX Extension) with ControlaBase class (Extenders are inherited from ExtenderBase). Why ajax toolkit provide only extender template? Have anybody used ControlBase class?

Hi,

Which ControlBase class are you referring to? There is only a ExtenderControlBase class that acts as the base class.

The main purpose of the template is to provide a better starting point for creating an Extender, some necessary logics has been added in the base class. Of course, you may choose a different base class, event Control class. But developers will have to do more in this case, and it's more error-prone.

Which ControlBase class are you referring to?

On the server side, the Ajax Control Toolkit defines two base classes: ExtenderControlBase and ScriptControlBase. The ExtenderControlBase class derives from the ExtenderControl class and is used to create extenders. The ScriptControlBase class inherits from the ScriptControl class and is used to create script controls.

On the client side, the Microsoft Ajax Library provides the Sys.UI.Behavior and Sys.UI.Control classes for creating visual components. In turn, the Toolkit API provides base classes that encapsulate additional functionality for creating behaviors and controls. These classes are called BehaviorBase and ControlBase.

These are two quotations from Manning ASP.NET AJAX IN ACTION
