I asked you why you wanted to access private members of UserControl in your
copying routine. What is your answer ?

As was mentioned in the MSDN thread, what you are trying to do is based on
unsound design and until you can justify what you are trying to achieve in
more detail, it is very difficult for anyone to give you an answer that
makes any sense.

The idea of using ICloneable in a derived class also means that you would
have to write a list of assignments of protected or public properties; that
is what cloning is all about, you don't have a choice.
