OnScaleFactorChanged Method (ImageBox)

protected virtual void OnScaleFactorChanged( 
   RoutedPropertyChangedEventArgs<double> e
)

'Declaration
 
Protected Overridable Sub OnScaleFactorChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Double) _
) 

'Usage
 
Dim instance As ImageBox
Dim e As RoutedPropertyChangedEventArgs(Of Double)
 
instance.OnScaleFactorChanged(e)

protected:
virtual void OnScaleFactorChanged( 
   RoutedPropertyChangedEventArgs<double>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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