This article shows how to get started with MVVM development for WPF applications.Separation of Concerns (decoupling) or So C is a principle that promotes best practices for software architecture.A ‘concern’ can be considered as an aspect of software functionality.For eg: The UI can be a concern, the business logic can be another concern and so on.

(bool)value; } } public class booleaninverter : IValue Converter { public object Convert(object value, Type target Type, object parameter, System.

Abstract: The MVVM Light toolkit provides a lot of boiler plate code to implement Model-View-View Model based applications quickly and gives the user the freedom to customize and design the application.

While the converter answers are all valid, you may want to look at an alternative methodology: Commanding.

In WPF (and somewhat in Silverlight), you can bind an ICommand to that button. Is Loaded; } ); } return _cancel Loading Command; } } that will invert your boolean values.

So, if you created, on your View Model, a property called Cancel Loading Command that implemented ICommand, you'd bind the button as follows: public ICommand Cancel Loading Command { get { if (_cancel Loading Command== null) { this._cancel Loading Command= new Relay Command( delegate { // Cancel the loading process. While creating this class is more difficult than adding a new property, it's completely reusable - so later, you can reuse this in other bindings (without polluting your View Model with lots of ! This class would look something like: [Value Conversion(typeof(bool), typeof(bool))] public class Invert Bool Converter : IValue Converter { public object Convert(object value, Type target Type, object parameter, Culture Info culture) { bool boolean Value = (bool)value; return !
