The panel has three text fields, name, address and details. It also has a
list. This may contain none or more phone numbers, so it could have a scroll
bar. There are also buttons that allow the user to add/edit/delete a phone
number.

When the user elects to edit a record, all the controls are enabled. When he
confirms or cancel his edits, all controls will be disabled.

That is except, I don;t want to disable the list as the user would want to
review the phone numbers without gong into edit mode.

Hope this helps.
