OnCrosshairChanged Method

Show in webframe





An EventArgs that contains the event data.
Raises the CrosshairChanged event.
Syntax
protected virtual void OnCrosshairChanged( 
   EventArgs e
)
'Declaration
 
Protected Overridable Sub OnCrosshairChanged( _
   ByVal e As EventArgs _
) 
'Usage
 
Dim instance As RasterMagnifyGlass
Dim e As EventArgs
 
instance.OnCrosshairChanged(e)

            

            
protected:
virtual void OnCrosshairChanged( 
   EventArgs^ e
) 

Parameters

e
An EventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. The OnCrosshairChanged 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 OnCrosshairChanged in a derived class, be sure to call the base class's OnCrosshairChanged method so that registered delegates receive the event.
