Add Header and Footer to an existing empty word document with OpenXML SDK 2.0

Question

I\'m trying to add a Header and Footer to an empty word document.

I use this code to add Header part in word/document.xml when change docx to zip.

Answer 1

this code worked for me. Take into consideration:

1. header's relationship Id is "r97" in my example. Perhaps you would like to decide a unique rId on your own
2. same for footer's relationshipId ("r98")
3. Both header and footer have a hardcoded paragraph with some text.

4. I am assuming a document already exists

               using (WordprocessingDocument doc = WordprocessingDocument.Open(destination, true))
               {
                   var mainDocPart = doc.MainDocumentPart;
                   if (doc == null) {
                       mainDocPart = doc.AddMainDocumentPart();
                   }
   
                   if (mainDocPart.Document == null)
                   {
                       mainDocPart.Document = new Document();
                   }
   
                   ApplyHeader(doc);
   
                   ApplyFooter(doc);
               }
   

ApplyHeader method:

public static void ApplyHeader(WordprocessingDocument doc)
      {
          // Get the main document part.
          MainDocumentPart mainDocPart = doc.MainDocumentPart;

          HeaderPart headerPart1 = mainDocPart.AddNewPart<HeaderPart>("r97");



            Header header1 = new Header();

            Paragraph paragraph1 = new Paragraph(){  };



            Run run1 = new Run();
            Text text1 = new Text();
            text1.Text = "Header stuff";

            run1.Append(text1);

            paragraph1.Append(run1);


            header1.Append(paragraph1);

            headerPart1.Header = header1;



            SectionProperties sectionProperties1 = mainDocPart.Document.Body.Descendants<SectionProperties>().FirstOrDefault();
            if (sectionProperties1 == null)
            {
                sectionProperties1 = new SectionProperties() { };
                mainDocPart.Document.Body.Append(sectionProperties1);
            }
            HeaderReference headerReference1 = new HeaderReference() { Type = HeaderFooterValues.Default, Id = "r97" };


            sectionProperties1.InsertAt(headerReference1,0);

        }

ApplyFooter method:

public static void ApplyFooter(WordprocessingDocument doc)
      {
          // Get the main document part.
          MainDocumentPart mainDocPart = doc.MainDocumentPart;

          FooterPart footerPart1 = mainDocPart.AddNewPart<FooterPart>("r98");



          Footer footer1 = new Footer();

          Paragraph paragraph1 = new Paragraph() { };



          Run run1 = new Run();
          Text text1 = new Text();
          text1.Text = "Footer stuff";

          run1.Append(text1);

          paragraph1.Append(run1);


          footer1.Append(paragraph1);

          footerPart1.Footer = footer1;



          SectionProperties sectionProperties1 = mainDocPart.Document.Body.Descendants<SectionProperties>().FirstOrDefault();
          if (sectionProperties1 == null)
          {
              sectionProperties1 = new SectionProperties() { };
              mainDocPart.Document.Body.Append(sectionProperties1);
          }
          FooterReference footerReference1 = new FooterReference() { Type = DocumentFormat.OpenXml.Wordprocessing.HeaderFooterValues.Default,  Id = "r98" };


          sectionProperties1.InsertAt(footerReference1, 0);

      }

Enjoy,

Answer 2

I find the solution by myself.

In fact, adding a header or a footer in a docx with OpenXml involves that :

Document has to exist.

Saving and closing document before adding a header or a footer does not work.

WordprocessingDocument document = WordprocessingDocument.Open(path, true);
<operations on docx>
document.Save();
document.Close();
ChangeHeader(document);

You have to re-open a second time your docx to create a new instanciation of the document.

Correct solution will be (with James Wood solution):

WordprocessingDocument document = WordprocessingDocument.Open(path, true);
<operations on docx>
document.Save();
document.Close();
ChangeHeader(path);

    public static void ChangeHeader(String documentPath)
    {
        // Replace header in target document with header of source document.
        using (WordprocessingDocument document = WordprocessingDocument.Open(documentPath, true))
        {
            // Get the main document part
            MainDocumentPart mainDocumentPart = document.MainDocumentPart;

            // Delete the existing header and footer parts
            mainDocumentPart.DeleteParts(mainDocumentPart.HeaderParts);
            mainDocumentPart.DeleteParts(mainDocumentPart.FooterParts);

            // Create a new header and footer part
            HeaderPart headerPart = mainDocumentPart.AddNewPart<HeaderPart>();
            FooterPart footerPart = mainDocumentPart.AddNewPart<FooterPart>();

            // Get Id of the headerPart and footer parts
            string headerPartId = mainDocumentPart.GetIdOfPart(headerPart);
            string footerPartId = mainDocumentPart.GetIdOfPart(footerPart);

            GenerateHeaderPartContent(headerPart);

            GenerateFooterPartContent(footerPart);

            // Get SectionProperties and Replace HeaderReference and FooterRefernce with new Id
            IEnumerable<SectionProperties> sections = mainDocumentPart.Document.Body.Elements<SectionProperties>();

            foreach (var section in sections)
            {
                // Delete existing references to headers and footers
                section.RemoveAllChildren<HeaderReference>();
                section.RemoveAllChildren<FooterReference>();

                // Create the new header and footer reference node
                section.PrependChild<HeaderReference>(new HeaderReference() { Id = headerPartId });
                section.PrependChild<FooterReference>(new FooterReference() { Id = footerPartId });
            }
        }
    }


public static void GenerateHeaderPartContent(HeaderPart part)

Answer 3

I'm quite sure what is wrong with your code, I suspect its the way you are changing the references.

In any case I have a working example which you should hopefully guide you.

I've based mine from examples here: http://msdn.microsoft.com/en-us/library/office/cc546917.aspx

I used the Open XML SDK 2.0 Productivity Tool to Generate the Header and Footer parts. I first create a document with my desired layout then open it with the tool, it generates the XML or Code. You can get it here: http://www.microsoft.com/en-us/download/details.aspx?id=5124

The only caveat to this is that it assumes the document already some content in the body, a single letter will do. I'm not sure if this can be avoided, I tried opening an empty document in the Productivity Tool and it suffers from the same error - "Cannot open the file: Archive file cannot be size 0". In my sample it will fail on WordprocessingDocument.Open.

Maybe in the case of an empty document you have to create a body first. In any case I suspect the main aim of this question is to add a header and footer so I feel this is a valid answer.

If you want I can provide the actual cs/project files.

Hope this helps.
