I wrote an entry sometime back in Jan 2011 to show how you can easily generate a Word document using the OpenXML SDK with font size, font color and bold formatting.
Yesterday, I received a comment from Hema, who asked me how to add subscript and superscript formatting.
To tell the truth, I had not dabbled in those before. But I decided since I have already come so far, I can just spend a little time to see if I can apply subscript and superscript effects to my previous code too.
I am glad I tried, because I realised its not too difficult. The only problem is that there’s little documentation out there, so I managed to arrive at the solution purely through my own ‘experiment’ and I am not sure if my method is the most efficient!
I am assuming that you are familiar with the OpenXML SDK and procedures such as how to create Run and RunProperties based on my previous post. What you need to add superscript or subscript is to use the “VerticalTextAlignment” class to specify if you wish to have a “Superscript” or “Subscript” or the default “Baseline” alignment.
Scroll below for the full code to generate a Word document with one single sentence with output like this:
public void GenerateSentence(string filename)
{
WordprocessingDocument doc = WordprocessingDocument.Create(filename,
WordprocessingDocumentType.Document);
MainDocumentPart mainPart = doc.AddMainDocumentPart();
mainPart.Document = new Document();
Body body = new Body();
/**** Create the contents ****/

run1 = new DocumentFormat.OpenXml.Wordprocessing.Run();
fs1.Val = "40";

vta4.Val = VerticalPositionValues.Baseline;

para = new Paragraph(run1);
body.AppendChild(para);
/*** Append the entire body ****/
mainPart.Document.Append(body);
/* Save the results and close */
mainPart.Document.Save();
doc.Close();
}//end GenerateSentence
NOTE: You might notice that when you open up the Word document, the spaces go missing. I had this problem too, and upon Googling, found out that this is due to a bug in Microsoft’s OpenXML Office 2010/2007 implementation. Oh well….
