Fri, 22 May 2009 18:06:09 GMT

Taking another look at how we can use the Observer Pattern in our application, but this time we will implement the pattern using call backs and events. The Observer pattern allows you to define a one-to-many relationship inside your application where the parent object (the one) has the ability to notify the child objects (the many) of any state change. You can utilize this pattern to make sure that a set of objects are keep in order when there behavior needs to change based on the state of your application.

Creating a Custom Observable Collection in WPF | UX and WPF ramblings

Thu, 14 May 2009 03:16:02 GMT

One of the biggest advantadges WPF has is its Data Binding features. Data Binding can be done in several ways, but the most common is using the INotifyPropertyChanged and INotifyCollectionChanged interfaces. For simple objects, all you need to do is implement the INotifyPropertyChanged, and raise the PropertyChanged event when your properties change. When you want to bind to a collection, you will want to use ObservableCollection<T>. This collection implements both interfaces, therefore notifying you when the items in the collection change and when the items' properties change. This works great if you're using standard collections. The problem arises when you want to use a custom collection. For databinding to work with custom collections, you will have to create a new "Observable" wrapper around it.
