eForm Fields Example

This example shows how to change the values of eForm fields. In this example we simply replace each of the fields in a form with the name of that field.

Src

First we create an ABCpdf Doc object and read in our template form.

using var doc = new Doc();
doc.Read(Server.MapPath("../mypics/form.pdf"));

doc.Form.NeedAppearances = false; // for PDF 2.0

Using doc As New Doc()
  doc.Read(Server.MapPath("../mypics/form.pdf"))

  doc.Form.NeedAppearances = False
  ' for PDF 2.0

Add

We iterate through each of the top level fields. For each field we set the value of the field to be equal to the value of the name.

string[] names = doc.Form.GetFieldNames();
foreach (string theName in names) {
  var field = doc.Form[theName];
  field.Value = field.Name;
}

  Dim theNames As String() = doc.Form.GetFieldNames()
  For Each theName As String In theNames
    Dim theField As Field = doc.Form(theName)
    theField.Value = theField.Name
  Next

Save

Finally we save.

doc.Save(Server.MapPath("eformfields.pdf"));

  doc.Save(Server.MapPath("eformfields.pdf"))
End Using

Results

Given the following document.

form.pdf

This is the kind of output you might expect.

eformfields.pdf
