title: xamarin forms: How can I close the tabbedpage and show the previous page when click a tab?
body: <p>I have a tabbed page in my xamarin forms project having 4 tabs. I am opening the tabbed page from the home page(normal content page) and initially showing 2nd tab.</p>
  
  <p>When I click the first tab I need to exit from the tabbed page and show the homepage (previous page) in UI.</p>
  
  <p>How can I do this? Is there any tabbed page events are available?</p>
