>I would not add a MemberClass to an existing class. You will need to create a new base class with the member class and then port over. I tried adding a MemberClass to a working grid once and it broke all kinds of things. The good news is that MemberClass works good if you use it right.

And then it's quite easy to write a builder which will replace the instances of the old class with those of the new.
