What is the common way to check the check box field in a pdf using iTextsharp?

Question

I am filling the data for a fillable pdf using iTextsharp. There are n number of checkboxes in the pdf form. I have set the value for the check boxes using "Yes" or "No". This works fine. But some of the check boxes does not work in this way; instead i need to use 1 or 0 to make it work. So can anyone help me what is the common way to check/uncheck the checkboxes in pdf using iTextSharp?

Thanks in Advance,

Answer 1

Open chosen PDF and convert it.

PdfReader reader = new PdfReader(fileNameIn);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(fileNameOut));
AcroFields form = stamper.getAcroFields();

Inspect the form objects Fields > Keys > Results view to find the string value of a Check Box, in my case is was "Check Box1"

String[] checkboxstates = form.GetAppearanceStates("Check Box1");

Inspect the checkboxstates variable. [0] = value of non checked, [1] = value of checked. Then to make it checked

fields.SetField("Check Box1", checkboxstates[1])

Answer 2

you can find in this way:

PdfReader reader = new PdfReader(fileNameIn);
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(fileNameOut));
AcroFields form = stamper.getAcroFields();

form.setField("Name","Test Name");
form.setField("odot","123456");
form.setField("Consortium","A Testing Co");
form.setField("PName","My Name");
form.setField("date","10/14/03");
form.setField("Box1","true"); //This is the checkbox control
stamper.close();

hope this help

There is no "common way". You need to know the check/uncheck values in order to change them.

There's a similar question I answered where I showed how to find out those values... Ah!
