OnLostFocus Method (RasterThumbnailBrowser)

protected virtual void OnLostFocus( 
   EventArgs e
)

'Declaration
 
Protected Overridable Sub OnLostFocus( _
   ByVal e As EventArgs _
) 

'Usage
 
Dim instance As RasterThumbnailBrowser
Dim e As EventArgs
 
instance.OnLostFocus(e)

protected:
virtual void OnLostFocus( 
   EventArgs^ e
) 

Parameters

e

An System.EventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

The OnLostFocus 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 OnLostFocus in a derived class, be sure to call the base class's OnLostFocus method so that registered delegates receive the event.

This example overrides the virtual events of the RasterImageList class.
