This interface has a single event that notifies the bindings that a particular property has changed and any bindings using it should re-evaluate their values.

We can implement it like this: Now the binding properly updates to show “Mark”.

In the ancient and cruel world of WPF you might want to populate a Text Block with a string which will contain data from different sources.

For example, you might want to display song and band in a single text Block like, “Where Do You Go – No Mercy”.

If you are just getting started with WPF I would suggest taking a look at this getting started guide.

Let’s look at the the three pieces of MVVM: Model, View, and View Model.

If you are using dependency injection, the model classes will typically be passed as interface constructor parameters in your view model.

Since the interaction between the view model and the model will largely depend on your specific application, for the rest of this article we will focus just on the interaction between the view and the view model.

Although the property’s value has been changed, there has been no notification to the Binding to update its value.

We can fix this by implementing the INotify Property Changed (INPC) interface.

The song name and band name can be two different fields in your class.
