Hi all, To perform any action on swiping a pivot page just write the code inside Pivot selection change event. For example if I have to enable or disable an app bar button on pivot change, I want button[2] to be disabled when we navigate on pivot page index 2.

private void pivotecontrol_SelectionChanged(object sender, SelectionChangedEventArgs e) { Pivot pivot = sender as Pivot; if (pivot == null) { return; } switch (pivot.SelectedIndex) { case 0: ((ApplicationBarIconButton)ApplicationBar.Buttons[2]).IsEnabled = true; break; case 1: ((ApplicationBarIconButton)ApplicationBar.Buttons[2]).IsEnabled = true; break; case 2: ((ApplicationBarIconButton)ApplicationBar.Buttons[2]).IsEnabled = false; break; case 3: ((ApplicationBarIconButton)ApplicationBar.Buttons[2]).IsEnabled = false; break; } }
