ASP.NET MVC Best Pratices

[fredpig]

I come from the WPF side of the world and I am used to using the MVVM pattern quite a bit. I am attempting to learn MVC and am having a little bit of dificulty trying to understand where my boundries are in MVC. Here is my scenario:I have 3 objects, Parent, Child and GrandChild. These are custom objects, not using the built in model stuff from MVC. I have a good handle on validation stuff. I have a good handle on how to get and populate my objects. But, I am struggling to find best practices on what to do with Controllers. What should my controller be responsible for? For example, should I have one controller that understands how to CRUD Parent, Child, and GrandChild? Or should those be separated? If they should be separated, how should I do that if, when I am looking at Parent, I want to see a list of Children.Any guidance on this subject or links to other blogs with information would be greatly appreciated. Thanks.
