- 30. Pull To Refresh!
- 31. The API
- 32. ViewModel Code
- 33. The XAML!
- 34. Styles • Now you can group into a Style and share! • Can also be added to App-‐level ResourceDictionary
- 35. Styles • DynamicResource behave like data-‐binding, and support Apple’s Dynamic Type (﴾size)﴿ rendering • Triggers & Behaviors can be added to styles
- 36. Triggers • Visual Elements can react to events and property changes • “conditional style” -‐ CP • Can be added in C# • Types: § Trigger § EventTrigger § DataTrigger § MultiTrigger OR OR
- 37. Triggers • The EventTrigger has Event instead of Property • TriggerAction is written in C# • Remember xmlns:
- 38. Triggers • DataTriggers can bind to other controls (﴾Binding instead of Property)﴿
- 39. Behaviors • Add functionality to visual elements without subclassing
- 40. Behaviors • Add functionality to visual elements without subclassing • Can participate in data-‐ binding
- 41. Basic Navigation! § Root Page:! § NavigationPage – Gives each page an INavigation ! ! § Standard Navigation! § Navigation.PushAsync(page: nextPage);! § Navigation.PopAsync();! § Modal Navigation! § Navigation.PushModalAsync(page: modalPage);! § Navigation.PopModalAsync();! ! !
- 43. Advanced Navigation! § Editing of stack beyond push/pop! § Remove Page! § InsertPageBefore! § NavigationStack[]! § Disable animations! ! !
- 46. Use Xamarin.Insights! It’s Free and Amazing!
- 47. • Real-‐time Monitoring for your Apps • iOS, Android, Mac, and Windows • Xamarin.com/Insights
- 48. • Automatically report any uncaught managed or native exception. • Report your own caught exceptions with simple cross-‐ platform API Report
- 49. • Track any event that occurs in your application. • Even track performance of how long an operation takes. Track
- 50. • Combine event tracking with user identification to resolve issues faster. Identify
- 51. • Simple integrations into popular services for mission critical notifications. Integrate
