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.
