You can use Ajax. Use AjaxControlToolKit[^], where in you can place server side controls in UpdatePanel, and write serverside code. Thus you can avoid postbacks. I hope this helps you. Cheers, Sudhanva

store two tables data in some variables when page is loading. then use javascript to change items in second dropdownlist. here are steps: 1. store country and state data in two hidden fields, or two variables in JavaScript. 2. write function to change items in second dropdownlist. ... Changing Select element content on the fly [^]

Glad to discuss with you and best wishes.
