OnIsVisibleChanged Method

Summary

Occurs when the value IsVisible property changes.

Syntax

C++

protected virtual void OnIsVisibleChanged( 
   RoutedPropertyChangedEventArgs<bool> e 
)

  
Protected Overridable Sub OnIsVisibleChanged( _ 
   ByVal e As RoutedPropertyChangedEventArgs(Of Boolean) _ 
)

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

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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