  • LINQ to SQL associations - how to change the value of associated field

    - by HAdes
    I have 2 classes with a LINQ association between them i.e.: Table1: Table2: ID ID Name Description ForiegnID The association here is between Table1.ID - Table2.ForiegnID I need to be able to change the value of Table2.ForiegnID, however I can't and think it is because of the association (as when I remove it, it works). Therefore, does anyone know how I can change the value of the associated field Table2.ForiegnID? Thanks.
