OnScreenDpiYChanged Method (ImageViewer)

protected virtual void OnScreenDpiYChanged( 
   RoutedPropertyChangedEventArgs<int> e
)

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

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

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

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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