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

You can also import the AcroForm data from FDF, XFDF, and TXT formats, as described below.

To import interactive forms from XML format:

  • load an interactive forms document (e.g., from a file path), in which the data will be imported, into the PDF Viewer using the PdfViewer.LoadDocument method;
  • call one of the PdfViewerExtensions.Import overloaded methods, for example, with a specified XML file that contains imported data.


You may need to add the DevExpress.Docs reference to your application to access the PdfViewer.Import extension methods.

    public partial class Form1 : Form {
        public Form1() {

            // Load a PDF document with AcroForm data.

            // Import the document from an XML format. 

            // Save the imported document.
