I want to create two dynamically dependent list boxes. The first one being the main which retrieves the data from the database and second one being the child. When a value in the first list box is clicked, the second one should get populated. I am not too comfortable with Arrays, is it possible to workout the solution in some other way. If possible please point me to some useful sites. Thanks in advance.

Just read the DB and populate the listbox. Asp101.com *may* have some examples.

You can put the first list in a FORM, and then click a submit button to send the selected value from the first list back to the page again, to populate the 2nd list.

You *may* want to investigate a javascript solution if your DB is small.

As mentioned, if your database is small you could use JavaScript to facilitate changing the menus without posting back to the server. A sample of the client side script is here. You'll just need your asp to generate the appropriate javascript options.
