OnSourceDpiXChanged Method (ImageViewer)

protected virtual void OnSourceDpiXChanged( 
   RoutedPropertyChangedEventArgs<int> e
)

'Declaration
 
Protected Overridable Sub OnSourceDpiXChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Integer) _
) 

'Usage
 
Dim instance As ImageViewer
Dim e As RoutedPropertyChangedEventArgs(Of Integer)
 
instance.OnSourceDpiXChanged(e)

protected:
virtual void OnSourceDpiXChanged( 
   RoutedPropertyChangedEventArgs<int>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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