In Acrobat Pro X, I can toggle the fields off and on as normal. If I introduce
1 << 14 (the 15th bit, No Toggle To Off), the behavior changes and clicking a
selected radio option no longer deselects it.
Opening the same PDF in Reader 9.4.2 demonstrates the same behavior.
Sounds like a problem on your end.

This is the exact code that's generating this :
// step 1
Document document = new Document();
// step 2
PdfWriter writer =
PdfWriter.GetInstance(document, new
FileStream(@"C:\Users\Andre\Desktop\testpdf.pdf", FileMode.Create));
// step 3
document.Open();
PdfContentByte canvas = writer.DirectContent;
Rectangle rect = new Rectangle(100, 100, 110, 110);
PdfFormField field;
PdfFormField radiogroup =
PdfFormField.CreateRadioButton(writer, false);
radiogroup.FieldName = "language";
RadioCheckField checkbox = new RadioCheckField(writer,
rect, "check1", "on_check1");
field = checkbox.RadioField;
radiogroup.AddKid(field);
rect = new Rectangle(120, 100, 130, 110);
checkbox = new RadioCheckField(writer, rect, "check2",
"on_check2");
field = checkbox.RadioField;
radiogroup.AddKid(field);
writer.AddAnnotation(radiogroup);
document.Close();
The checkboxes are around the bottom somewhere, and you'll need form
highlighting to see them as I removed the bits of code adding the borders while
I was cleaning my test of anything extraneous.
If it makes any difference, I'm using Adobe Reader 9.4
Thanks for all the help.

confusion exists on your end is largely because I said: "CreateRadioButton

I'm sorry.
So, from the top. You're not setting NO_TOGGLE_TO_OFF
anywhere, either via the "CreateRadioButton(writer, false)", or via
RadioCheckField.options. Yet you are getting the "no toggle to off" behavior.
Correct?
Could you attach your PDF? I'd like to check for the presence
of the flag despite your best efforts, and see the behavior for myself in
Acrobat Pro where I can properly disect it.

Sorry, I'm not sure which extra parameter you're
referring to. By createCheck() do you mean the method that created the parent
field or that creates the kid field? If it's the latter, iTextSharp doesn't
have methods like that, instead you have lines like PdfFormField field =
checkbox.RadioField; (RadioField being a property of the RadioCheckField class,
or possibly it's base class, I'm not sure, but it's a property, and not a
method, and thus I have no way of changing how it behaves short of extending
the iTextSharp class and overriding it, which seems rather excessive for this).
As for the parent's behaviour, you said that the
CreateRadioButton() method only creates the appearance, so how would I change
the options of the parent field itself? Right now, the kid fields are being
added to the PdfFormField which is initialized to whatever CreateRadioButton()
returns, so I would assume that that PdfFormField is the parent, but I can't
set any related (checkbox/radiogroup specific) options on it (at least not in
any way I can tell).

Ah.
Okay, then just drop the extra parameter in the
createCheck() call (or change it to false, same results). The kids were
inheriting the parent's behavior. And don't set the kid's option either.
Final Point: If you're using some Off Brand
PDF viewer, they may not have implemented the "toggle to off" behavior in the
first place (or they have a bug).

Subject: Re: [iText-questions]
iTextSharp RadioGroup noToggleToOff notworking.
Thanks for the reply, but I think one
of us of misunderstanding something..
checkbox.Option |=
PdfFormField.FF_NO_TOGGLE_TO_OFF; looks to me like that would set the
checkboxes to NOT be uncheckable. This is the behaviour that I want to remove,
i.e. I want the checkboxes to be uncheckable, so that their behaviour would be
something like this :
given checkboxes A and B, both starting
unchecked, click A->A is checked, click B->A is unchecked and B is checked,
click B->B is unchecked.
If it helps at all, here's a simplified
example that should be runnable on it's own (note that as it's iTextSharp, it
would need to be changed a bit to work in Java with plain old iText) :
Document document = new
Document();
PdfWriter writer =
PdfWriter.GetInstance(document, new
FileStream(@"C:\Users\Andre\Desktop\testpdf.pdf", FileMode.Create));
document.Open();
PdfContentByte canvas =
writer.DirectContent;
Rectangle rect = new
Rectangle(100, 100, 110, 110);
PdfFormField field;
PdfFormField radiogroup =
PdfFormField.CreateRadioButton(writer, false);
radiogroup.FieldName =
"language";
RadioCheckField checkbox =
new RadioCheckField(writer, rect, "check1", "on_check1");
checkbox.Options |=
PdfFormField.FF_NO_TOGGLE_TO_OFF;
field = checkbox.RadioField;
radiogroup.AddKid(field);
rect = new Rectangle(120,
100, 130, 110);
checkbox = new
RadioCheckField(writer, rect, "check2", "on_check2");
checkbox.Options |=
PdfFormField.
field = checkbox.RadioField;
radiogroup.AddKid(field);
writer.AddAnnotation(radiogroup);
document.Close();

Took me a couple readings of the code
to figure this one out myself.
CreateRadioButton creates the visual
element for a radio button field, not the parent field under which the kids
reside. The "no toggle off" behavior should be in the individual child fields,
not the parent.
The parent field is working, so that's
clearly not a big deal. And to fix your button creation code, you need to add:
checkBox.options |=
PdfFormField.FF_NO_TOGGLE_TO_OFF;
No that isn't one of the listed options
in BaseField's JavaDoc. The full list of valid options are all the
PdfFormField.FF_* contstants, some of which are duplicated in BaseField without
the leading FF_.

Subject: [iText-questions] iTextSharp
RadioGroup noToggleToOff not working.
Here are the bits of code in question :
[code]
PdfFormField group1 =
PdfFormField.CreateRadioButton(writer, false);
group1.FieldName = "group1";
group1.AddKid(CreateCheckBox(over, "check1", 8.5f, 363, 459.8f + GIFLOffset_1,
0.3f));
group1.AddKid(CreateCheckBox(over, "check2", 8.5f, 471, 459.8f + GIFLOffset_1,
0.3f));
writer.AddAnnotation(group1);[/code]
and the CreateCheckBox method :
[code]
private static PdfFormField
CreateCheckBox(PdfContentByte layer, String name, float size, float llx, float
lly, float thickness)
{
PdfFormField field;
RadioCheckField checkbox;
Rectangle rect = new
Rectangle(llx, lly, llx + size, lly + size);
checkbox = new
RadioCheckField(layer.PdfWriter, rect, name, "on_" + name);
checkbox.CheckType =
RadioCheckField.TYPE_CHECK;
checkbox.BackgroundColor =
BaseColor.WHITE;
checkbox.BorderColor =
BaseColor.BLACK;
checkbox.BorderStyle =
PdfBorderDictionary.STYLE_SOLID;
checkbox.BorderWidth = 0.4f;
checkbox.FieldName = name;
field = checkbox.RadioField;
layer.Rectangle(rect);
layer.SetLineWidth(0.4f);
layer.Stroke();
return field;
}[/code]
This code is part of a larger program
that generates a customized document. The checkboxes are created fine and show
up properly, and I can check one or the other (but not both) as expected,
however they cannot be unchecked at all.
I was under the impression that the
false value passed into the CreateRadioButton method should make it so that you
can uncheck a box so that neither will be checked, but even changing that to
true had no effect on behaviour (that behaviour being that once one of the
checkboxes is checked, one will always be checked unless a reset button
elsewhere on the form is clicked).
Any help getting the checkboxes to be
uncheckable would be greatly appreciated.
