I have a a user control which contains sevral other user controls. I am using MVVM. Each user control has a corresponding VM. How do these user controls send information to each other. I want to avoid writing any code in the xaml code behind. Particularly I am interested in how the controls (inside the main user control) will talk to each other and how will they talk to the container user control.

EDIT: I know that using events-delegates will help me solve this issue. But, I want to avoid writing any code in xaml code-behind.
