Creating a OOXML document with Track Changes enabled - openxml

Question

How do I create a .docx with track changes enabled? I was told inside word/settings.xml I should modify w:proofState but all info in online docs of OOXML I find about that property is related to grammar and spell checking, but nothing about enabling tracking changes.

Answer 1

It is in word/settings.xml but the element you are looking for is w:trackRevisions.
To do this in C# using the OpenXML SDK you can use the TrackRevisions class. The following code will create a document with one paragraph and with change tracking turned on:
using (WordprocessingDocument package = WordprocessingDocument.Create(filename, WordprocessingDocumentType.Document))
{
// Add a new main document part.
package.AddMainDocumentPart();
//create a body and a paragraph
Body body = new Body();
Paragraph paragraph = new Paragraph();
paragraph.AppendChild(new Run(new Text("This document should have change tracking switched on")));
body.AppendChild(paragraph);
package.MainDocumentPart.Document = new Document(body);
//change tracking code
DocumentSettingsPart documentSettingsPart = package.MainDocumentPart.AddNewPart<DocumentSettingsPart>();
Settings settings = new Settings();
TrackRevisions trackRevisions = new TrackRevisions();
settings.Append(trackRevisions);
documentSettingsPart.Settings = settings;
// Save changes to the main document part.
package.MainDocumentPart.Document.Save();
}
