OnImageChanged Method






An EventArgs that contains the event data.
Raises the ImageChanged event.
Syntax
protected virtual void OnImageChanged( 
   EventArgs e
)
'Declaration
 
Protected Overridable Sub OnImageChanged( _
   ByVal e As EventArgs _
) 
'Usage
 
Dim instance As RasterImageViewer
Dim e As EventArgs
 
instance.OnImageChanged(e)
protected virtual void OnImageChanged( 
   ~Remove~ e
)
 function Leadtools.WinForms.RasterImageViewer.OnImageChanged( 
   e 
)
protected:
virtual void OnImageChanged( 
   EventArgs^ e
) 

Parameters

e
An EventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. The OnImageChanged 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 OnImageChanged in a derived class, be sure to call the base class's OnImageChanged method so that registered delegates receive the event.
Do not confuse this with Leadtools.RasterImage.OnChanged(Leadtools.RasterImageChangedEventArgs).
Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
