In a form I used dropdownlist ,

I used a two dropdownlist.
I need to select an item from dropdownlist1, then its corresponding some details
show in dropdownlist2.
I implemented it by set Autopost back=True.
But when I select an option the page will reload, so it is very slow.
How to avoid this problem.

You can use JQuery and Json with Webservice to populate another dropdownlist on the base of selected value in the first dropdownlist.
