Universal Windows® Apps with XAML and C# Unleashed

Other Ways to Use Frame

Not every app needs to follow the pattern of a Window hosting a Frame that hosts Page(s). A Window’s content doesn’t have to be a Frame, and you can embed Frames anywhere UIElements can go. We can demonstrate this by modifying a Hub App project to set the Window’s Content to a custom Grid subclass that we create. Imagine this is called RootGrid, and it must be constructed with a Frame that it wants to dynamically add to its Children collection. It would be used in App.xaml.cs as follows:

// Instead of Window.Current.Content = rootFrame: Window.Current.Content = new RootGrid(rootFrame);

RootGrid can be added to the project as a pair of XAML and code-behind, shown in Listings 7.3 and 7.4.
