Null DataContext

We haven't initialized the Profile property yet and so it's null. Because of that, the entire <div> and its contents won't be rendered. We can use this feature to hide parts of the page whenever we want.

Tasks

Let's write some code to initialize the Profile property on demand.

• In the Load method, initialize the Profile property to a new instance of Profile.
• In the Unload method, set the Profile property to null.
