clientside event on Radio Button List selection

[sanbatra]

Hello,

I have a Radio Button List containing 5 elements. I require that on selection of any radio button, a drop down list box gets populated (from database - needs to go to server) depending upon the selection in radio button list.
but how can I avoid teh complete post back of the page and still be able to achieve the functionality.
I am new to asp.net and web technologies. Plz help.

Regards,
Sanjeev
