OnIsVisibleChanged Method

Summary

Occurs when the value IsVisible property changes.

Syntax

C#
VB
C++
protected override void OnIsVisibleChanged( 
   RoutedPropertyChangedEventArgs<bool> e 
) 
Protected Overrides Sub OnIsVisibleChanged( 
   ByVal e As RoutedPropertyChangedEventArgs(Of Boolean) 
) 
protected:  
   virtual void OnIsVisibleChanged( 
      RoutedPropertyChangedEventArgs<bool>^ e 
   ) override 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Return Value

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.
