OnIsClosedChanged Method

protected virtual void OnIsClosedChanged( 
   RoutedPropertyChangedEventArgs<bool> e
)

'Declaration
 
Protected Overridable Sub OnIsClosedChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Boolean) _
) 

'Usage
 
Dim instance As AnnPolygonObject
Dim e As RoutedPropertyChangedEventArgs(Of Boolean)
 
instance.OnIsClosedChanged(e)

protected:
virtual void OnIsClosedChanged( 
   RoutedPropertyChangedEventArgs<bool>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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