Ciao intrepidosul2,
non mi sei sembrato molto convinto per l'ASP.NET ...
Comunque ... ti ho "personalizzato" un po' la pagina che avevi già visto (quel link che avevo proposto) ed eccola di seguito.
La pagina l'ho chiamata "Prova.asp" tu rinominala come vuoi, però attento: devi andare a modificare il listbox delle regioni dove c'è inserito il nome della pagina ...
Il funzionamento della pagina è abbastanza semplice. Se non selezioni nessuna regione e nessuna provincia, premendo il bottone "Cerca", avrai l'elenco completo delle scuole. Se invece selezioni una regione, la pagina si ricarica (c'è un javascript nell'opzione "onChange" del listbox) e si popola il listbox delle province. Anche in questo caso se non selezioni la provincia, avrai l'elenco di tutte le scuole in quella regione, se invece selezioni anche la provincia, avrai l'elenco delle scuole nella provincia ...
Un'ultima cosa: nel file incluso "Scuole.asp" c'è definita la variabile MM_Scuole_STRING per la connessione al database.
Spero di essere stato chiaro ... fammi sapere, ciao
Umb
