Just set the form.datasession=2 (private) and that's it. You need to do that in edit mode, when it instantiates at runtime it's too late.

There's a catch, though - many SET commands are scoped to the datasession, so such settings that you may have in place in the main .prg of your app will need to be set again for each form. Most frameworks solve this by calling some sort of setenvironment prg (or method) in form's .load method. For a list of such settings, see help for SET DATASESSION Command.
