Hi.....

Please any one give me some idea.... I want develop a web application in asp.net for a restaurant. That web application should accept orders from users. But i dont know how to accept multiple dish orders to insert into database.

Means how to save temporarily in webpage before saving in database? for the user to edit and display the orders dish items.


Thanks and Reagrds

You could store 'Order' objects in cookies or the cache.
