ASP Autofill form

Hi!
I just found your website and it's terrific.
I need to know if an Autofill form can be made. The language is ASP.
My programmer says it's not possible, is it true?

The idea is to have a search button where the customers inputs the letters of product models (the info comes from a DB) and it's autocompleted or at least, the system searches for the closest model no. ; once the customer clicks on the model they want, all info regarding that model would be displayed in another form.

Can it be done?

Thanks for your help!!!
