Hi everyone,

I’m working on merging two or more PDF pages into a single page using the "DrawCapturedPage" function. This works fine overall, but I’ve run into a problem:

The form fields that I previously filled using "SetFormFieldValueByTitle" remain empty in the merged PDF page.

Does anyone have an idea how I can ensure that the contents of the form fields are retained when merging the pages?

Thanks in advance for your help!

Hi :)

It's necessary that each form field has a unique name. If you put several pages with form fields on a new single page you should have an eye on this fact if you don't want to run into problems.

Another point: What type of form fields you're using? Acro or xfa? QuickPDF doesn't offer much support using xfa.

Cheers,
Ingo

Hi Ingo,

Thank you for your answer.

It doesn't work even with a single field (I tested it to rule out potential issues with duplicate names).
The form was originally created with LibreOffice. How can I find out the type of the form fields?
I am using the DebenuPDFLibraryDLL1811.
If merging the pages doesn't work this way, I’m considering how to place all fields on one page and delete the unnecessary ones before saving/printing.

Greetings
