You're not really doing anything wrong, it's just that the SetSQLStrings
method is only going to be called when you actually assign a value to
the property. Changing the Text property of the Tstrings doesn't do
that, it's just modifying the object. If you use a TStringList, it has
OnChange and OnChanging events that you can set up to do what you want.
Make sure also that your SetSQLStrings uses .Assign and not := to change
the value of the fSQLStrings as well (I presume you are already doing
this).

Cheers,
Paul
