OnShowLengthChanged Method (AnnPolyRulerObject)

protected virtual void OnShowLengthChanged( 
   RoutedPropertyChangedEventArgs<bool> e
)

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

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

'Usage
 
Dim instance As AnnPolyRulerObject
Dim e As RoutedPropertyChangedEventArgs(Of Boolean)
 
instance.OnShowLengthChanged(e)

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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