one to many relationship - PersonID and Person fields are not updated in Child

[orit1]

hi,
I have a Person class
Person is a parent of an Address, the relation is one to many (parent has many Addresses)
like that (taken from the constructor of Person):
Addresses = new ChangeTrackingCollection

();

I need when I add Address to person like that:
addresses .Add(new Address())
the properties Person and PersonID in Address getting values according to the Person

how can I do this?
do I need to used with Parent field from ChangeTrackingCollection class? If so how?

Thanks in advance

@orit1, Thanks for the question. You don't have to populate these fields on the client. They will be populated by EF on the server when the entity is saved.

thanks for your response
in our system is needed, Is there a nice way to do that?

Another important thing -
If I work connect, the fields get values on the server like you said
But if I'm working dissconnect also on the server it doesn't happen
Is there a way to work dissconnect and that the fields fill up?

I see now. In order to populate related fields (foreign keys, reference properties), you will need to do this yourself for disconnected entities.
