The WordMeister

In my last post I described how to achieve a continuous section break in Word Open XML. In this post, I go into how to force the continuous section break in the middle of a paragraph.

Section breaks are inserted by creating a SectionProperties element within a Paragraph element. The SectionType determines whether the break will be Continuous, Next Page, Even Page or Odd Page. Only the first of these can be located within a paragraph. That this presents a logical problem is clear, since the SectionProperties must be a child element of a Paragraph.

Building on the XML in my previous post, you can see that I’ve added the Run and Text child elements to the first paragraph with the text “Before section break”. This is followed by an additional paragraph. Inside the Run you can see the element <w:lastRenderedPageBreak/>. The Open XML SDK documentation doesn’t even hint that the LastRenderedPageBreak is also used to trigger the visual display of a continuous section break within a paragraph…

<w:p><w:pPr><w:sectPr w:rsidR=”0008038F” w:rsidSect=”00C26E80″>
  <w:type w:val=”continuous”/>
   <w:pgSz w:w=”11906″ w:h=”16838″/>
   <w:pgMar w:gutter=”0″ w:footer=”708″ w:header=”708″ w:left=”1417″ w:bottom=”1134″ w:right=”1417″ w:top=”1417″/>
   <w:cols w:space=”708″/><w:docGrid w:linePitch=”360″/>
</w:sectPr></w:pPr>
<w:r><w:t>Before section break </w:t></w:r></w:p>
<w:p>
  <w:r>
    <w:lastRenderedPageBreak/>
    <w:t xml:space=”preserve”> after section break</w:t
  ></w:r>
</w:p>

Here’s the result of the XML…

…and here is the code used to add such a section break to an existing document. It does not produce the sample XML code, above. It inserts a continuous section break after the first run of the first paragraph in the document.

private void btnContSecBrk_Click(object sender, EventArgs e)
{
string fileName = @"C:\Test\DocSecBreaks.docx";
using (WordprocessingDocument pkgDoc = WordprocessingDocument.Open(fileName, true))
{
Body b = pkgDoc.MainDocumentPart.Document.Body;
//The type of following section break determines
//the type of preceding section break.
SectionProperties secNext = b.Descendants().FirstOrDefault();
SectionType secType = secNext.Elements().FirstOrDefault();
if (secType==null) {
secType = new SectionType { Val=SectionMarkValues.Continuous};
secNext.InsertAt(secType, 0); }
else {
secType.Val = SectionMarkValues.Continuous; }

//Second paragraph contains all but first run of original,
//So that first run original with its child elements
//can be removed from the cloned paragraph.
rFirstWord.RemoveAllChildren();
rFirstWord.Remove();
//The LastRenderedPageBreak will be inserted
//before the first Run of the cloned paragraph.
Run r = pNew1.Elements().FirstOrDefault();
LastRenderedPageBreak brk = new LastRenderedPageBreak();
Text t = r.Elements().FirstOrDefault();
r.InsertBefore(brk, t);
pNew2.InsertAfterSelf(pNew1);
//Remove the original paragraph at the end.
pFirst.RemoveAllChildren();
pFirst.Remove();
}
}
