PHP Класс Prado\Web\UI\ActiveControls\TActiveButton

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