Class TActiveButton
TActiveButton is the active control counter part to TButton.
When a TActiveButton is clicked, rather than a normal post back request a
callback request is initiated.
The onCallback OnCallback event is raised during a callback request
and it is raise after the onClick OnClick event.
When the TBaseActiveCallbackControl::setEnableUpdate
ActiveControl.EnableUpdate property is true, changing the setText Text
property during callback request will update the button's caption upon callback
response completion.
