Thanks very much.

Yes, I thought maybe it was just a limitation of the PDF radio button behavior, but thought I'd check to see if maybe a trick could be deployed.

I followed your suggestion and after iterating to the next record added a "None" radio button.

Works like a charm.

I'm now writing logic to check to see if any values within the group are checked. If not checked then the "None" radio button have its value set.

If I get something that works reasonably well and can be used by anyone else, I'll post the Delphi code excerpts since this must be a pretty common problem.

Thanks again.

the very first time the developer setting works.

After this - at runtime - there's no possibility to reset to startsetting.

I think this is normal behavior...

if you want to integrate your described functionality you could insert an additional checkbox or a button linked with some javascriptcode doing this job for you.

An easier way: A fourth choice with the text "nothing" ;-)

 

Cheers and welcome here,

However, once selected, they stay selected.

As an example, if I have three choices with none selected,

if I select choice one, and change my mind to select another

it works fine, but, if I want to reverse my selection to none,

it appears there is no backing out.

Thanks in advance for any help.
