Click button in dynamic XFA forms from C#

Hi, I have some dynamic XFA forms which were built using Adobe LiveCycle Designer. This forms have Add/Remove button. to add or remove particular section. for example, if there are more then 1 company name then you can click the add button which will add another text box to write 2nd company name. I am filling this forms from C# using ASPOSE PDF and I do not know how to click these button from C# to add another section(subform) if I have multiple data. I have attached the screenshot as well to …

I have a PDF XFA form that has a button click which adds additional form fields to the document. How can I programatically ‘click’ this button (or run the code behind it) from C# to generate the additional form fields?

Hi Ali,

I have actually figured out how to do this - I simply have to specify the row number in the field name when filling out the XFA form and the PDF will dynamically expand to accommodate the data. However, I’m having trouble with the signature field now. I am not sure how to do this exactly for an XFA form’s signature field.

Thank you for the feedback.

Would you please share SSCCE code along with source PDF file and some more details about the problem you are facing with signature field.

@Farhan.Raza Unfortunately I’m not even sure how to start here with the Signature field. I’ll PM you the code I’m using to fill out the rest of the form as well as the form itself.

Thank you for sharing the file.

We have noticed that the PDF document is encrypted with permission password where filling of form is allowed but signing is restricted. Therefore, we are afraid Adobe Acrobat may not sign it either.

Interesting. I can sign it in Adobe acrobat, are you sure we can’t do it programmatically?

We have investigated further and would like to update you that Aspose.PDF currently does not support signing XFA form and a feature request with ID PDFNET-34530 is logged in our issue management system. This thread has been linked with the same ticket so that you may be notified as soon as the feature is supported.
