How to: Export the AcroForm Data

• May 24, 2019

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

Call the PdfViewerControl.ExportFormData method in the PdfViewerControl.DocumentLoaded event handler. This method invokes the Save As dialog, where you can specify a desired file format (XML or FDF) and the file name.
