+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.
+
+
+Active panel updated on callback: + |
+ a checkbox: a textbox: a label: +When you press the button, the panel contents will change. Note that out of the +panel and the button, all the other controls are not active but gets updated +anyway since they are placed inside the active panel. + |
