Does Spire.PDFviewer for WPF support fillable pdf forms?

[Xiangz]

I'd like to display a fillable PDF file in my WPF application.
The users can input data into the fields and save to a file as they can do with adobe PDF viewer externally.
Thanks

Dear Xiangz,

Thanks for your inquiry.
Sorry that Spire.PDFViewer doesn't support to fill pdf forms, it is just a viewer, and cannot operate PDF files.
Yet Spire.PDF supports the function, maybe you could use it.

Does Spire.PDF have UI, which display the PDF form, so that users can input the field data directly?

Dear Xiangz,

Thanks for your response.
Sorry, Spire.PDF doesn't have UI, and it only can handle the PDF document programmatically.
