TActivePanel

TActivePanel is the TPanel active control counterpart. TActivePanel allows the client-side panel contents to be updated during a callback response using the render method. Example: Assume $param is an instance of TCallbackEventParameter attached to the OnCallback event of a TCallback with ID "callback1", and "panel1" is the ID of a TActivePanel. function callback1_requested($sender, $param) { $this->panel1->render($param->getNewWriter()); }
