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.

You can enumerate over any collection that implements the IEnumerable interface.

First I bound Item Source property in XAML than i set Display Member Path to First Name it means Listbox should display only values of First Name property available in Collection.

In many cases the data that you work with is a collection of objects.

For example, a common scenario in data binding is to use an Items Control such as a List Box, List View, or Tree View to display a collection of records.

Note To fully support transferring data values from binding source objects to binding targets, each object in your collection that supports bindable properties must implement an appropriate property changed notification mechanism such as the INotify Property Changed interface.

Returns a filtered collection of elements that contains the descendant elements of every element and document in the source collection.

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.
