Open “MainPage.xaml” and add this markup: But for simplicity, I’ll show you how to set a custom title bar in MainPage only, but for sure you can follow the same steps to set it in a Master page or based on your own needs. But what if you want to have only one custom title bar for all the pages in your application! In this situation, you can add a Master page, add the custom title bar in it, then add a Frame control in that Master page to navigate through the other pages. Does that mean you can have two or more pages in your application, each of them with a different title bar with a different design?! Answer is YES. The custom title bar can be a XAML control or container inside the view that you are customizing its title bar. After that you need to set the title bar with your customized one. To customize title bar for a view you need to tell Windows runtime that you will replace the default window title bar for that view with your own.
