Upto my knowledge NO. Because radiobuttonlist will be rendered as individual HTML radio buttons. Once you made AutoPostback to true, ASP.NET will add a javascript function to this radio buttons for posting the form. So you won't be able to call your javascript function on radiobutton click to prevent page from posting. To do this I suggest use individual radio buttons. If you don't know the number of radio button's at design time, then put a ContentPlaceHolder and add radio button controls there with your custom javascript function to post data.

Yes Navneeth is right instead of using the radiobutton List you can use radio buttins with same name attribute. if you have written any javascript then doucment.getElementByName will return you all same name radiobuttons Now here you can make auotpost back property true or false to any radio button

If you are adding individual radio buttons to RadioButtonList at run-time then, before adding a radio button, set its "AutoPostBack" property to 'TRUE' or 'FALSE' as per your requirement.
