OnPointsChanged Method (AnnPolylineObject)

protected virtual void OnPointsChanged( 
   RoutedPropertyChangedEventArgs<PointCollection> e
)

'Declaration
 
Protected Overridable Sub OnPointsChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of PointCollection) _
) 

'Usage
 
Dim instance As AnnPolylineObject
Dim e As RoutedPropertyChangedEventArgs(Of PointCollection)
 
instance.OnPointsChanged(e)

protected:
virtual void OnPointsChanged( 
   RoutedPropertyChangedEventArgs<PointCollection^>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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