clientside event on radiobuttonlist selectedindexchange

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 the 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

Do a search for ASP.NET AJAX then. It'll allow you to use javascript to call a page or a service which returns data to you, you then can use the returned data to populate the dropdownlist.

Thanks for your reply.
I will check for the same.
