How do I Handle Business Logic Exceptions?

How du I access Session in the partiel method like  OnValidate? I want to set a field to a session-variable on every insert.

if (action == System.Data.Linq.ChangeAction.Insert)

{

  Id = Guid.NewGuid();

  AccountId = Session("AccontId"); // Current account

}

You would need to use HttpContext.Current.Session, but I think you'd be tying your model objects to the Session which could limit your design's usefulness in other projects.

Hi Scott. How can I implement business logic in the Delete-Insert-Update/Object partial method in the DataContext partial class? Thanks in advance.
