title: XAMARIN Button with Label and image inside / mainpage=navigation page
body: <p>I am fairly new and inexperienced. I have two questions. First: what would the xaml code in xamarin look like for such a button? The blue one should be the button. The button should contain a text and a picture. So it should also work that when the image or text is clicked, the button is actually clicked.

  Second: my app has two sides. The start page is MainPage and the other page is Page1. I can switch to Page1 using a button on MainPage. I looked at a tutorial and in App.xaml.cs &quot;MainPage = new MainPage ();&quot; was made to &quot;MainPage = new NavigationPage (new MainPage ());&quot;. Why was that done? Why does the page change via a button click not work differently?

  Since it was coded to &quot;MainPage = new NavigationPage (new MainPage ());&quot; , there is a blue bar at the top of my MainPage. How can I remove this bar or make it white?
