Development Platforms

Apps

  • Silverlight 3.x
  • XAML UI Framework
  • .NET
  • Metro Design
  • Rapid Application Development

Design Patterns

slide-7
SLIDE 7

Why use design patterns?

  • Separation of concerns
  • Colaboration
  • Blendability
  • Lookless view logic
  • No duplicated code to update views
  • T

estability

MVVM – Model View ViewModel

  • It„s just pattern!
  • Build into Silverlight & WPF
  • Can be extended with frameworks & helpers

MVVM commands

  • “Point of entry” for a method
  • Can be data bound
  • ICommand interface
  • Execute method
  • CanExecute method
  • CanExecuteChanged event
slide-13
SLIDE 13

MVVM messaging

  • Communication between ViewModels and

Views  loose coupling

  • Should be simple by default
  • Possible to open filtered channels
  • To a target Type (or an Interface)
  • With a Token
