Overview of this book

Need to ensure you can always create the best Windows apps regardless of platform? What you need are solutions to the biggest issues you can face, so you can always ensure you’re making the right choices and creating the best apps you can. The book starts with recipes that will help you set up the integrated development environment before you go ahead and design the user interface. You will learn how to use the MVVM design pattern together with data binding, as well as how to work with data in different file formats. Moving on, you will explore techniques to add animations and graphics to your application, and enable your solution to work with multimedia content. You will also see how to use sensors, such as an accelerometer and a compass, as well as obtain the current GPS location. You will make your application ready to work with Internet-based scenarios, such as composing e-mails or downloading files, before finally testing the project and submitting it to the Windows Store. By the end of the book, you will have a market-ready application compatible across different Windows devices, including smartphones, tablets, and desktops.

Applying styles programmatically


According to the information presented in the two previous recipes, you can use styles to easily adjust the design of your application. However, do you know that you can also apply styles programmatically? Thus, you can dynamically control the appearance of user interface. In this recipe, you will learn how to get data of the style defined in the page resources and apply it to an element with a suitable type.

As an example, you will prepare a page that presents four images. By default, they have a black border with a width of 3 pixels and its opacity set to 30%. After clicking on each image, its opacity should be changed to 100% and the border color should be set to blue. You will solve this problem by defining two styles, namely for active and inactive elements and applying a proper style after tapping on the photo.

Getting ready

To step through this recipe, you will only need the automatically generated project.
