I am trying to read a radio buttons using following code:
Field f = PDFDocument.GetField("radioButtonName");
if (f.GetType() == Field.Type.e_radio) {
pdftron.SDF.Obj values = f.GetValue();
}
f.GetValue() is null and I am unable to get its button value.
I want to get the button value, which I can use it later on to set
that radio button in another copy of pdf.
Q: This was very helpful, thank you. We have the list-box controls
working
correctly now. Do you have an equivalent code sample for radio
buttons?
Also, I looked in the documentation but there doesn't seem to be a
listing
for the fields in these objects that PDFTron provides. Is there some
part
of the documentation that we missed?

A: Radio buttons have only on/off state. You could GetValueAsBool() to
find out if the given radio button field is selected or not.
