The following classes provide the basic infrastructure classes required to -realize the active controls.
+realize the active controls. They can be useful to develop new active controls, but Prado users tipically don't need +to use them.+ TActiveControlAdapter customizes the parent TControl class for active control classes. + It tracks changes in the viewstate values of the control and update + differences of the client-side HTML element attributes. +
++ TActiveListControlAdapter allows the adapted list controls to change the selections + on the client-side during a callback request. +
+ TActivePageAdapter process the page life-cycle for callback requests. +
+ TBaseActiveControl class provided additional basic properties common for every + active control. An instance of TBaseActiveControl or its decendent + TBaseActiveCallbackControl is created by TActiveControlAdapter::getBaseActiveControl() + method. + The EnableUpdate property determines wether the active + control is allowed to update the contents of the client-side when the callback + response returns. +
+ TCallbackResponseAdapter alters the THttpResponse's outputs. + A TCallbackResponseWriter is used instead of the TTextWrite when + createHtmlWriter is called. Each call to createHtmlWriter will create + a new TCallbackResponseWriter. When flushContent() is called each + instance of TCallbackResponseWriter's content is flushed. + The callback response data can be set using the ResponseData property. +
The following classes provide advanced properties and events needed to realize the active controls. +A Prado user can use them to customize active controls behaviour and interact directly with the client side during a callback. +
