OnKeyDown Method (RasterThumbnailBrowser)

protected virtual void OnKeyDown( 
   KeyEventArgs e
)

'Declaration
 
Protected Overridable Sub OnKeyDown( _
   ByVal e As KeyEventArgs _
) 

'Usage
 
Dim instance As RasterThumbnailBrowser
Dim e As KeyEventArgs
 
instance.OnKeyDown(e)

protected:
virtual void OnKeyDown( 
   KeyEventArgs^ e
) 

Parameters

e

A System.Windows.Forms.KeyEventArgs that contains the event data

Raising an event invokes the event handler through a delegate.

The OnKeyDown method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors When overriding OnKeyDown in a derived class, be sure to call the base class's OnKeyDown method so that registered delegates receive the event.

This example overrides the virtual events of the RasterImageList class.
