| Leadtools.Controls Namespace > InteractiveService Object : OnKeyUp Method | 
function Leadtools.Controls.InteractiveService.onKeyUp( e )
| Parameter | Type | Description | 
|---|---|---|
| e | InteractiveKeyEventArgs | Event data | 
Raising an event invokes the event handler through a function. The OnKeyUp method also allows derived classes to handle the event without attaching a function to the event. This is the preferred technique for handling the event in a derived class.
Note to Inheritors: When overriding OnKeyUp in a derived class, be sure to call the base class's OnKeyUp method so that registered delegates receive the event.
