Radio Button Behavior

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I like the mutual exclusivity of the radio buttons.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.

John

	Hi John, 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, Ingo
	Cheers, Ingo

	Ingo, 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. John
