How to: Export the AcroForm Data

• Jun 20, 2018

This example shows how to export AcroForm data (interactive form data) from a PDF document to XML or FDF format.

To do this, call the PdfViewerControl.ExportFormData method in the PdfViewerControl.DocumentLoaded event handler.

This method invokes the Save As dialog window, where you can specify a desired file format (XML or FDF) and the file name.
