Wpf listview itemssource not updating

It's called Observable Collection, and you use it much like a regular List - that's all it takes!

This will make the Add and Delete button work, but it won't do anything for the "Change name" button, because the change will happen on the bound data object itself and not the source list - the second step will handle that scenario though.

Obviously you only have to call Notify Property Changed in the setter's of the properties that you bind to - the rest can remain the way they are.

This is just as easy, but once you start doing it, you might discover something that disappoints you: Changes are not automatically reflected, like they were in previous examples.

Observable Collection raises a Collection Changed event whenever an item is added or removed - the Items Source binding will listen for this event and refresh appropriately.

The Visibility binding, however, will only listen to Property Changed event, which is not raised when the collection changes.

The example is pretty simple, with a User class that will keep the name of the user, a List Box to show them in and some buttons to manipulate both the list and its contents.

The Items Source of the list is assigned to a quick list of a couple of users that we create in the window constructor.
