Filling the Gaps: How to Build a Custom Control in Xamarin.Forms

Xamarin.Forms provides a wide variety of basic cross-platform native mobile controls, but sometimes you need to step out of the box and build your own. At Xuni, that’s our gig: we create custom controls. Soon you will, too.

This 40-page white paper walks through basic to advanced scenarios, Xamarin structure, and platform-specific requirements.

You’ll learn how to:

  • Extend out-of-the-box Xamarin.Forms controls
  • Get more functionality in Xamarin.Forms with custom renderers and dependency services for iOS and Android
  • Create and implement a native custom control from the ground up and use it in Xamarin.Forms
