Observablecollection listbox not updating

Only elements that have a matching XName are included in the collection.

The item is deleted from the collection but the List View is not reflecting it.

The following example will show you why we need these two things: Try running it for yourself and watch how even though you add something to the list or change the name of one of the users, nothing in the UI is updated.

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.

If you have an advanced scenario and want to implement your own collection, consider using IList, which provides a non-generic collection of objects that can be individually accessed by index.

As you will learn in this article, you need just a bit of extra work for this to happen, but fortunately, WPF makes this pretty easy.This is the price you will have to pay if you want to bind to your own classes and have the changes reflected in the UI immediately.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.The Items Source of the list is assigned to a quick list of a couple of users that we create in the window constructor.The problem is that none of the buttons seems to work. The first step is to get the UI to respond to changes in the list source (Items Source), like when we add or delete a user.
