Answer 1

You are initializing a UIBarButtonItem without a handler. So tapping the button does nothing.

Try this:

    UIBarButtonItem button = 
    new UIBarButtonItem(UIBarButtonSystemItem.Refresh, 
                        (s, e) => Console.WriteLine("Refresh!"));

You can also assign it after initialization:

UIBarButtonITem button = new UIBarButtonItem(UIBarButtonSystemItem.Refresh);
button.Clicked += (s, e) => Console.WriteLine("Refresh!");

EDIT:

Inside the handler, you must implement your own “Refresh” code, depending on what it is you want to refresh. The UIBarButtonSystemItem enumeration merely defines the appearance of UIBarButtonItem buttons.
