Filling data in PDF continuation pages

2 mins read

It is possible to fill field data in WinForms PDF continuous pages using TryGetField method in PdfFormFieldCollection class. It helps to get form fields from an existing document using the field name. It specifies whether the field is available by returning a Boolean value, and then the field is filled.

Assemblies Required:

  1. Syncfusion.Pdf.Base.dll
  2. Syncfusion.Compression.Base.dll

The below code illustrates how to fill data in PDF continuation Pages.

Code Snippet:

//Load the PDF document 
PdfLoadedDocument page1Document = new PdfLoadedDocument("../../Data/FormPage.pdf");
//Load the Continuous PDF document 
PdfLoadedDocument pageContinuationDocument = new PdfLoadedDocument("../../Data/FormContinuationPage.pdf");
//Gets the form field collection from Loaded document
PdfLoadedFormFieldCollection form = page1Document.Form.Fields;
//Gets the form field collection from Continuous document
PdfLoadedFormFieldCollection formContinuation = pageContinuationDocument.Form.Fields;
//Sets Field as PdfLoadedTextBoxField
PdfLoadedField FirstName = null;
if (form.TryGetField("FirstName", out FirstName))
     (FirstName as PdfLoadedTextBoxField).Text = "Andrew";
     (FirstName as PdfLoadedTextBoxField).ReadOnly = true;
PdfLoadedField LastName = null;
if (form.TryGetField("LastName", out LastName))
     (LastName as PdfLoadedTextBoxField).Text = "Fuller";
     (LastName as PdfLoadedTextBoxField).ReadOnly = true;
PdfLoadedField FirstNameContinuation = null;
if (formContinuation.TryGetField("FirstName", out FirstNameContinuation))
     (FirstNameContinuation as PdfLoadedTextBoxField).Text = "Andrew";
     (FirstNameContinuation as PdfLoadedTextBoxField).ReadOnly = true;
PdfLoadedField LastNameContinuation = null;
if (formContinuation.TryGetField("LastName", out LastNameContinuation))
     (LastNameContinuation as PdfLoadedTextBoxField).Text = "Fuller";
     (LastNameContinuation as PdfLoadedTextBoxField).ReadOnly = true;
//Creates new Pdf Document
PdfDocument doc = new PdfDocument();
//Append the Loaded document to new document and dispose it                  
//Sets the PdfDocument Form as Read only
doc.Form.ReadOnly = true;
//Save the document and dispose it
