Wpf mvvm listview not updating
The XAML looks like this: using a data binding to my Selected Names property.With that in place the Selected Names collection in my View Model is updated whenever Selected Items on the List Box changes.

Have you found that you can understand the basics of data binding in WPF and Silverlight, but when you start to read about Model-View-View-Model (MVVM) you find that you have been dropped off a cliff?Fairway Technologies is a premier provider of expert technology consulting and software development services, helping leading firms convert requirements into top-quality results. Have you looked at some of the XAML frameworks like PRISM only to find that it is just way too complicated for what you need?The Two List Synchronizer code does not make especially thrilling reading, so I won’t show it here.The interesting thing to me about MVVM (Model-View-View Model), is that the Model should know about nothing else, the View Model should only know about the Model (not the View), and the View should only know about the View Model (and not the Model).
View: This should just bind to the View Model and make stuff look pretty.The getter returns the current value of the property.The View will get this value when it is first bound and then it will only change when it receives a property change notification.When the setter is called with a new value, the property backing field is updated and then the event is raised to inform observers that the value has changed.
