PdfDocumentProcessor.GetFormData() Method

Returns an object containing values of interactive form data fields.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Docs.v20.2.dll


public PdfFormData GetFormData()
Public Function GetFormData As PdfFormData


Type Description

A PdfFormData object.


After the interactive form is changed, previously obtained interactive form data becomes invalid. The following operations change the interactive form:

  • add new fields;
  • flatten the form;
  • merge documents with interactive forms;
  • delete pages with interactive form fields.

Call the GetFormData method again to get valid interactive form data.


// Load a document with an interactive form.
using (PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor()) {
    documentProcessor.LoadDocument(filePath + fileName + ".pdf");

    // Obtain interactive form data from a document.
    PdfFormData formData = documentProcessor.GetFormData();

    // Specify the value for FirstName and LastName text boxes.
    formData["FirstName"].Value = "Janet";
    formData["LastName"].Value = "Leverling";

    // Specify the value for the Gender radio group.
    formData["Gender"].Value = "Female";

    // Specify the check box checked appearance name.
    formData["Check"].Value = "Yes";

    // Specify values for the Category list box.
    formData["Category"].Value = new string[] { "Entertainment", "Meals", "Morale" };

    // Obtain data from the Address form field and specify values for Address child form fields.
    PdfFormData address = formData["Address"];

    // Specify the value for the Country combo box. 
    address["Country"].Value = "United States";

    // Specify the value for City and Address text boxes. 
    address["City"].Value = "California";
    address["Address"].Value = "20 Maple Avenue";

    // Apply data to the interactive form. 

    // Save the modified document.
    documentProcessor.SaveDocument(filePath + fileName + "_new.pdf");
