Hi!

Add When method to the control and put the code in the GotFocus event:

if empty(this.When())
  this.enabled=.F.
else
  this.enabled=.T.
endif

So whenever you use this class, When event will be still available.

BTW, if you do nto want to disable control when it has no access, but just disable the access, you can do following in GotFocus event:

if empty(this.When())
  nodefault
endif

Nodefault command in GotFocus event prevent control to get focus.

HTH.
