Populate XFA Form Fields Values in PDF Document using Aspose.PDF

I am working on a project and looking to buy something to populate PDF form for my client.
I tried to use ASPOSE PDF to populate fields on a government form, but it does not work for all fields. I believe this form is created by LiveCycle and user can add section to the PDF dynamically.
I was able to extract all field names using the script below:

var allFields = “”;

for (var i = 0; i < this.numFields; i++)
var newField = ‘"’ + this.getNthFieldName(i) + '" ';
allFields += newField;

But the problem is some fields cannot be populated, e.g.: form1[0].page2[0].householdMember[1].memberLastName[0]

Here is the url to download the form. It’s a government form:



Thank you for contacting support.

Would you please share the code which you are using to populate the fields in your environment, along with generated PDF document so that we may investigate further to help you out.

Hi Farhan,
I am still investigating and see if it’s possible to populate this PDF form. My code is really simple, just trying to populate some values into fields and see if the code is working. Here is my code:

Aspose.Pdf.Facades.Form form = new Aspose.Pdf.Facades.Form(“C:\temp\TempProject\PDFTest\PDFTest\PDF\Trillium Application Form.pdf”);

        string aaa = form.FieldNames.ToString();

        form.FillField("form1[0].page1[0].section2[0].contactPerson[0].lastName[0]", "last name test");

        //form.FillField("form1[0].page1[0].section2[0].contactPerson[0].#subform[0].gender[0]", "Male");
        form.FillField("form1[0].page1[0].section2[0].contactPerson[0].#subform[0].gender[0]", "Female");

        form.FillField("form1[0].page1[0].section2[0].contactPerson[0].MailingAddress[0].StreetName[0]", "mailing address test");
        form.FillField("form1[0].page1[0].section2[0].contactPerson[0].residentialAddress[0].StreetName[0]", "residential address test");
        form.FillField("form1[0].page2[0].householdMember[0].memberLastName[0]", "member 1 last name");
        form.FillField("form1[0].page2[0].householdMember[1].memberLastName[0]", "member 2 last name");
        form.FillField("form1[0].page2[0].householdMember[2].memberLastName[0]", "member 3 last name");
        form.FillField("form1[0].page2[0].section3[0].insurance[0].insurancePlan[0].phLastName[0]", "insurance plan ph last name");

        //form.FillField("form1[0].page2[0].section3[0].drug[0].sub[0].radio[0].Yes[0]", true);

        form.FillField("form1[0].page2[0].section3[0].drug[0].sub[0].radio[0]", "Yes");

        form.Save("C:\\temp\\TempProject\\PDFTest\\PDFTest\\PDF\\Trillium Application Form_TryFill.pdf");

Here is the original document I downloaded from the government website: Trillium Application Form_Original.pdf (1.6 MB)

Here is the one I populated: Trillium Application Form_TryFill.pdf (1.6 MB)

I also noticed when I open the one I populated, I got a message and it said the document has been changed and extended feature is no long available. Is it possible to use ASPOSE.PDF to populate PDF without modifying the document?
