What you need to do is have 2 different AppBars in your application - the first with the 2 ApplicationBarIconButtons (Refresh and Favorite) and the second with only the Refresh ApplicationBarIconButton.

In your EventHandler for ApplicationBarIconButton_Click_1, you can change the AppBar that is currently being displayed to the user.

Something like this works...

ApplicationBar appBar1 = new ApplicationBar();
ApplicationBarIconButton refreshIcon = new ApplicationBarIconButton();
refreshIcon.text = "Refresh";
refreshIcon.Click += new EventHandler(Refresh_Click);
appBar1.add(refreshIcon);

ApplicationBarIconButton favIcon = new ApplicationBarIconButton();
favIcon.text = "Refresh";
favIcon.Click += new EventHandler(Fav_Click);
appBar1.add(favIcon);

ApplicationBar appBar2 = new ApplicationBar();
ApplicationBarIconButton refreshIcon2 = new ApplicationBarIconButton();
refreshIcon2.text = "Refresh";
refreshIcon2.Click += new EventHandler(Refresh_Click);
appBar2.add(refreshIcon2);

ApplicationBar = appBar1; // Assign the AppBar with both buttons as the default.

Then in the EventHandler for Fav_Click, write

ApplicationBar = appBar2; // This will make the AppBar with only "Refresh" button visible giving the impression that the Favorite button has been made invisible.

You cannot set visibility of individual buttons in the app bar to collapsed. But you can enable/disable them by using the IsEnabled property or remove them dynamically from your code behind ApplicationBar.Buttons.Remove(object) and pass the button object which you receive on click event. I guess it should work.
