public event EventHandler Unload
/** @event */

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

Server controls must perform any final clean-up, such as closing files, database connections and discarding objects, during this stage of the control lifecycle before the instance is unloaded.
