I need to subscribe to an event for a control when ContentControl.Content is set.

Please, what event can I put in my code to set it?

From this webpage:

The strange approach to receiving notifications of changes in dependency properties involves dynamically creating both a dependency property and data binding. If you're writing a class that descends from DependencyObject, have access to an object that contains dependency properties, and need to be notified when one of those dependency properties changes, you can create a dependency property and a binding on the fly to give you the information you need.

ContentControl.Content is a dependency property.
