hi, I am developing an application where i am having 2 combo boxes and those combo boxes were populated by the value from databases.I have populated my 1st combo box by using a Java bean where i have used sql query.But for populating the 2nd combo box i need to use another bean where i have to give the selected value of the 1st combo box in the where condition of its SQL query.
It sounds as if you are trying to mix client and server-side code, and that just can't happen. Please read this article to find out why.
What you are trying to do has pretty much become the "poster child" example for using Ajax to retrieve the dynamic context of the secondary select element (by the way, it's not a "combo box", there is no such native control on the web).
Search the HTML forum for "dependent dropdown" or "cascading dropdown" for many previous disucssions of just this issue. [ October 01, 2007: Message edited by: Bear Bibeault ]
