How to Fill an Acroform PDF Document

The following steps illustrates filling Acroform form fields of a PDF document using DynamicPDF Core Suite. Acroform form field values are set to the field by accessing the field using its name. The value that is specified must match the form field export value in order to select the field (ex: check box, radio button etc). Unicode values are fully supported.

Steps for setting values on a merged Acroform in PDF

  1. Create a MergeDocument object.
  2. Set the field values.
  3. Save the PDF document.

Sample Code - C#

MergeDocument document = new MergeDocument(Util.GetPath("Resources/PDFs/fw9AcroForm_18.pdf"));

           document.Form.Fields["topmostSubform[0].Page1[0].f1_1[0]"].Value = "Any Company, Inc.";
           document.Form.Fields["topmostSubform[0].Page1[0].f1_2[0]"].Value = "Any Company";
           document.Form.Fields["topmostSubform[0].Page1[0].FederalClassification[0].c1_1[0]"].Value = "1";
           document.Form.Fields["topmostSubform[0].Page1[0].Address[0].f1_7[0]"].Value = "123 Main Street";
           document.Form.Fields["topmostSubform[0].Page1[0].Address[0].f1_8[0]"].Value = "Washington, DC  22222";
           document.Form.Fields["topmostSubform[0].Page1[0].f1_9[0]"].Value = "Any Requester";
           document.Form.Fields["topmostSubform[0].Page1[0].f1_10[0]"].Value = "17288825617";


How to do AcroForm Filling and Reorganizing in C#

The following steps and sample code illustrates merging two PDF documents containing Acro Form fields and reorganizing their names with name prefixes.

Steps for Appending a Prefix to Form Feld Names and Fill

  1. Create a MergeDocument object with a MergeOptions object that specify a prefix for form fields.
  2. Append a second pdf document into the MergeDocument with a MergeOptions object that specify a prefix for form fields.
  3. Set the field values using both prefixes and name (new name).
  4. Save the PDF document.

Sample Code - C#

MergeDocument document = new MergeDocument( "source.pdf", new MergeOptions( true, "fw_4" ) );
document.Append( "source.pdf", new MergeOptions( true, "fw_9" ) );
document.Form.Fields["fw_4.FirstName"].Value = "John";
document.Form.Fields["fw_9.FirstName"].Value = "John";
document.Draw( "output.pdf" );
