WPF: Changing an item in a collection observed by ListView

Question

I have a ListView (with a GridView) bound to a collection of items. This is pretty standard stuff. The collection is an ObservableCollection.

Now let's say I change some property of an item in the collection. How do I tell the ListView about this? The list is tens of thousands of lines long, so I need to be able to tell it not to reload the entire collection, just that I updated some single element.

Any ideas?

If your objects implement some kind of property change notification (the most common way is to implement the interface INotifyPropertyChanged) - then the list will know to update the property change automatically.
