Radiobutton checked value bug: works in all pdf viewers except Acrobat Reader.

Report · Sep 04, 2020

"Checked" radiobutton value is only working in Acrobat Reader when:

First radio button value is "0".
Radio button values are consecutive integers.

In the PDF file the radiobuttons are not checked.

Hallo Bernd.

Exactly, so the default "checked" works for any values of the checkbox in all other pdf viewers.

In Acrobat Reader, however, default "checked" only works if the radio buttons (with the same name) have values 0, 1, 2 etc, mandatory starting with value 0.

Beste Grüße, Dmitriy.

E.g. when I look in the PDF file at Radio 2 both radio buttons are set to Off. So no button is checked when you open the file in Acrobat Reader.
