Thank you for the information - I am able to discover and fill the form fields in the XFA document with the information you provided.

I have one more question: Can you digitally sign an XFA document from Aspose? I am able to see how to do it in a regular Acrobat doc, but I can not find any documentation on how to do in in XFA.

Thanks for your help

Moreover in reference to digitally signing an XFA form. Please check documentation to digitally sign PDF file, It should work. However if you find any issue then please share your sample PDF document here. We will look into it and will guide you accordingly.

Best Regards,

I am unable to sign the XFA form. I can update/fill fields, but the signing does not produce any results or errors. As requested, here is the code and sample document that I am attempting to sign.

Please let me know if you need any other information

Thanks

Hi Chris,


Thanks for your patience.

As per our understanding, XFA forms cannot be signed. So in order to sign the document, please either convert them to Static or Standard format and then try signing them. For further details, please visit Convert Dynamic XFA Form to Standard AcroForm
