Is there a way to do it?
Thanks in advance,
as far as I understand, the radio buttons are rendered by HTMLB by using a TableView with SingleSelection, right? In this case, what you can retrieve is the TableView JS object. For this, JS methods exist to ask which row is selected, see ie5controls.js (or so, don't have file access at the moment).
If you need further assistance, please submit is minimized example of your JSP, DynPage, or AbstractPortalComponent, depending on what you are using.
I addition, please be a bit more responsive than you have been in and Consider rewarding points for helping answers, that's the SDN way to say "thank you, good help". If proposals didn't work, also this would be nice to give as feedback information, for the people trying to help as well as for others running into the same issue.
Hope it helps
