Yes.

You need to have AJAX-enabled website. Web.Config needs a change accordingly.
Easiest would be to create a new AJAX-Enabled website and then copy-paste the web.config from that to your current one.

Make sure, you put Scriptmanager and Updatepanel on your page. (with dropdowns inside updatepanel)
