è possibile creare delle combobox popolate dinamicamente in base alla  
scelta del utente nelle form?  
mi spiego ho una form con

Nome Text  
Regione Combobox  
Città Combobox

vorrei che a seconda della regione che l’utente sceglie si popolasse la  
combobox città con le citta presenti in quella regione

ovviamente ho 2 tabelle  
tabella regions  
id nome

tabella cities  
id nome region\_id
