How to Fill AcroForm

The following steps and C# sample code illustrate how to fill a PDF AcroForm programmatically using DynamicPDF Core Suite for .NET.

Steps for Filling an AcroForm

1. Create a new MergeDocument instance.
2. Set the field values by specifying the field name and the desired value.
3. Add the Draw method to output 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";
document.Draw("output.pdf");

How to Reorganize and Fill AcroForm

The following steps and C# sample code illustrate using DynamicPDF Core Suite for .NET to merge two PDF documents containing AcroForms and then reorganizing the combined AcroForm field names with name prefixes.

Steps for Reorganizing and Filling an AcroForm

1. Create a MergeDocument instance, and in the constructor, specify a MergeOptions instance that specifies a prefix for its form fields.
2. Append a second PDF document to the MergeDocument instance and specify a MergeOptions instance that specifies a prefix for its form fields (unique from the previous form's prefix).
3. Set the field values using the new unique names (prefix and original names).
4. Add the Draw method to output the PDF document.

Sample Code - C#

MergeDocument document = new MergeDocument("fw9AcroForm_18.pdf"), new MergeOptions(true, "fw_9A"));
document.Append("fw9AcroForm_18.pdf"), new MergeOptions(true, "fw_9B"));
document.Form.Fields["fw_9A.topmostSubform[0].Page1[0].f1_1[0]"].Value = "Any Company A, Inc.";
document.Form.Fields["fw_9A.topmostSubform[0].Page1[0].f1_2[0]"].Value = "Any Company A";
document.Form.Fields["fw_9B.topmostSubform[0].Page1[0].f1_1[0]"].Value = "Any Company B, Inc.";
document.Form.Fields["fw_9B.topmostSubform[0].Page1[0].f1_2[0]"].Value = "Any Company B";
document.Draw("output.pdf");
