GESTIONE E-SHOP
file:
shop.ashx           - elaborazione richieste Ajax
shop.js             - gestione eventi lato client
shop.ascx           - carrello e file .NET
menu.ascx           - carrello piccolo
conferma.ascx       - conferma ordine ed elaborazione paypal
shopping_cart.cs    - classe con tutti i metodi di calcolo, info pagamenti, generazione random order
registrazione.ascx  - registrazione utente
shop.mdb            - database

1) Inserire <div id='shop'></div> su menu.ascx (per carrello piccolo) e shop.ascx (carrello completo)
2) Quando siamo su shop.ascx, rendere non visibile il <div> su menu.ascx (utilizzano gli stessi ID)
3) Solo email e password per accesso sono lato server(ctl_15), questo per la validazione dei form
4) <div id='my_alert'></div> (per le finestre di alert) è su menu.ascx, se non si usa il carrello piccolo metterlo su shop.ascx
