When i save a new entity in db, the generatet identificator (guid.comb), is received and the container control is updated.
Now when the entity is saved in the db, a trigger is called by sql server and generate two record in a related table.
How can i, automatically receive new records ?

you can't do that automatically. But you can have code in your save method for that object that refreshes the collection so that the newly created objects are loaded.

OK. Thanks
