strongly typed list of objects that can be accessed by index

ObservableCollection is a generic dynamic data collection
that provides notifications (using an interface "INotifyCollectionChanged")
when items get added, removed, or when the whole collection is refreshed.
|
INotifyPropertyChanged is not a collection, it’s an
interface used in the data object classes to providePropertyChanged notification
to clients when any property value gets changed. This will allow you to raisePropertyChanged event
whenever the state of the object changes (Added, Removed, and Modified) to
the point where you want to notify the underlying collection or container
that the state has changed.

Using this you can search, sort, and manipulate lists

INotifyPropertyChanged is compatible on all type of
collections like List<T>, ObservableCollection<T>, etc.
|
To Update the list you need to bind the data source again.
|
It does not provide any notifications when any property in the
collection is changed.
The values in the observable collection are added, removed and
changed during runtime in the code behind. The operations (adding and
removing an item) in the observable collection will be updated to the UI (Datagrid).
But any change in the existing item will not be updated to the UI.

ObservableCollection
From the msdn documentation:
It represents a dynamic data
collection that provides notifications when items get added, removed, or when
the whole list is refreshed.
public class ObservableCollection<T> :
Collection<T>, INotifyCollectionChanged, INotifyPropertyChanged
|
Notice that, like any collection that derives from
Collection<T>, its methods accept null
parameters and do not throw an exception.
But the main feature of the ObservableCollection<T> are the
events it raises when the items it contains change.
By implementing the
INotifyCollectionChanged and INotifyPropertyChanged interfaces, the collection
has events for CollectionChanged and PropertyChanged. All these events are
related. The first one is raised whenever something changed in the collection,
be it Add, Remove, Move, etc.
This also trigger the PropertyChanged event for
the Items[] property. When you’re adding or removing items,
PropertyChanged is also raised for the Count property.
