title: Xamarin.Forms - How to disable Tab on TabbedPage?
body: <p>I'm looking for a way to disable a tab within a TabbedPage. The tab should be still showing up in the TabbedPage header but simply be disabled.</p>
  
  <p>I tried to set the Page to IsEnabled = false but apparently this is not how you do it or I did it wrong. :)</p>
