Add choices to an existing dropdown list

Aspose.PDF Product Family
1

Hi!


I’ve got a PDF document created by Adobe LiveCycle Designer ES2 that I would like to edit using Aspose.Pdf.

My goal is to create the document using Adobe LiveCycle, leave the dropdown list empty, and fill the choices using code.

I’ve tried using a FormEditor & a Facade to achieve this, but without any success so far (it doesn’t seem to find the fields although they are indeed inside the XFA of the document).

I also tried accessing the XFA as mentionned here :
https://forum.aspose.com/t/99293
But also without success.

I am using the 9.5.0.0 version, .NET framework 4.0

I have attached a very simple example of a pdf file with a dropdown I would like to edit

Could you provide me with some help ?
Thanks !

Regards

Hi Mathieu,

Customer’s document contains XFA form. That’s why XML template of the document must be updated in order to add choice.
Please use the following snippet:

Document doc = new Document("37348.pdf");

string[] fields = doc.Form.XFA.FieldNames;

XmlNode node = doc.Form.XFA.GetFieldTemplate(fields[0]);

XmlNode items = node.SelectSingleNode("tpl:items", doc.Form.XFA.NamespaceManager);

XmlNode item = items.OwnerDocument.CreateNode(XmlNodeType.Element, "text", items.NamespaceURI);
item.InnerText = "Choice  # 4";
items.AppendChild(item);

doc.Save("37348-out.pdf");

Please feel free to contact us for any further assistance.

Best Regards,
