Setting this property affects the value of IsVisible, which in turn may raise the IsVisibleChanged event. However, IsVisible has other factors that influence it, for instance the visibility settings of parents that contain it.

Elements where Visibility is not Visible do not participate in input events (or commands), do not influence either the Measure or Arrange passes of layout, are not in a tab sequence, and will not be reported in hit testing.

The following example implements a handler that references two different named buttons that are intended to be a mutually exclusive pair in the user interface. Prior to running the actual program logic associated with the button, the button itself is set to be Visibility.Hidden, and the other button in the pair is set to Visibility.Visible.

public void PlayMedia(object sender, MouseButtonEventArgs args)
{
    pauseBTN.Visibility = Visibility.Visible;
    playBTN.Visibility = Visibility.Collapsed;

    media.SpeedRatio = 1.0;
    media.Play();
}
