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

Load a document with interactive forms (e.g., from a file path) into the PDF Viewer using the DocumentViewerControl.OpenDocument method.
Call the PdfViewerControl.ImportFormData method in the PdfViewerControl.DocumentLoadedEvent event handler.
To save the imported document, (e.g., to a file), call the PdfViewerControl.SaveDocument method with a specified file name, including a file path where the imported document will be located.
