Attach Login Username as Default Value for the form field

Based on the multi tenancy example, I did the following and is working.

In the form I don't ask for the User (or the Quote Date), I take care of that behind doors, because I don't want the user to touch it.

private class MySaveHandler : SaveRequestHandler<MyRow> {
            protected override void SetInternalFields()
            {
                base.SetInternalFields();

                if (IsCreate)
                {
                    Row.UserId = Authorization.UserId.TryParseID32();
                    Row.QuoteDate = DateTime.Today;
                }
            }
        }
