include id value hiddenly with auto complete with image

Hello in the following link, an article of yours titled auto complete with image, i have a doubt

http://www.aspsnippets.com/Articles/Configuring-jQuery-AutoComplete-Plugin-to-display-Images-in-ASP.Net.aspx

I am developing a movie database website and in that i included this auto complete with image feature for suggesting film names with the image of the film,film title and year of the film when the user types the first few words of a film.There is a button "search" next to the auto complete text box and if the user clicks that button it will take it to another page with the film title as query string and in that page i have written code to fetch details from database based on the film title query string. My problem is i want to fetch the details of the film in the page load event with the film_id value also i don't want to show the film_id value in the auto complete text box. How can i achieve this, please help me.

 To be simple i want the film_id value of the film title that the user selects as the query string which is used as search condition in the redirected page because there can be two film titles with the same name
