PHP Class Prado\Web\UI\ActiveControls\TActivePanel

TActivePanel allows the client-side panel contents to be updated during a callback response using the {@link 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());
}
