So all we need to do in the XAML file is to specify the binding member for each column.
We can do that by the "Display Member Binding" attribute and "Binding" markup extension.
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 second step is to let our custom User class implement the INotify Property Changed interface.By doing that, our User objects are capable of alerting the UI layer of changes to its properties.So far in this tutorial, we have mostly created bindings between UI elements and existing classes, but in real life applications, you will obviously be binding to your own data objects.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.
It looks like this: As you can see, implementing INotify Property Changed is pretty easy, but it does create a bit of extra code on your classes, and adds a bit of extra logic to your properties.
