Hi,

You can bind your controls to :

A. form properties 
    1. initially empty
    2. filled when record retrieved
    3. Stored back to record for update

B. Cursor columns
    1. Create cursor in Load event
    2. Append from record retrieved
    3. pass updates to SQL cursor for update

C. Dynamic assignment
    1. Empty control source property setting
    2. Control source string stored in comment
    3. When record is retrieved load control sources from comment

Just some suggested approaches to control source management.
