Inside the PanoramaItem that has the Header “categories,” let’s add a Grid and a Button control, as shown in Listing 2-12 and Figure 2-13. Listing 2-12. Adding a Grid and Button to Our PanoramaItem 40 CHAPTER 2  GET CONTROL: EXPLORING WINDOWS PHONE CONTROLS Figure 2-13. The appearance of our new Grid and Button By adding a Click event handler to this button, we can then execute any code we want.

Add a static property to return a single book with pre-filled data, as follows: public static Book ABook { get { return new Book() { Title = "Programming Windows Phone", Authors = "Jesse Liberty and Jeff Blankenburg", ISBN = "143023816X", Publisher = "Apress" }; } } 5. 54 Finally, add a property to return a list of Book object so that we can populate a list box, as follows: CHAPTER 3  GET THE DATA public static List Books { get { return new List() { new Book() { Title = "Programming Windows Phone", Authors = "Jesse Liberty and Jeff Blankenburg", ISBN="143023816X", Publisher = "Apress" }, new Book() { Title = "Programming Reactive Extensions and LINQ", Authors = "Jesse Liberty and Paul Betts", ISBN = "1430237473", Publisher = "Apress" }, new Book() { Title = "Programming Windows 8", Authors = "Jesse Liberty", ISBN = "TBD", Publisher = "Apress" }, }; } } Now we’re ready to create a couple TextBox controls which we’ll bind two properties of a book to.

Each of these moves used code similar to that in Listing 2-14, which means that when the user uses the Back button to navigate to the first page of our application, it’s 42 CHAPTER 2  GET CONTROL: EXPLORING WINDOWS PHONE CONTROLS actually going to take three confusing clicks to get there. In short, the back stack on the phone doesn’t match the back stack in your user’s head. Now imagine that your user decides to start entering dozens of categories at once. They could require more than 20 Back button presses to get back home.
