Can anybody guide me how to add predefined styles on paragraph using open XML Word Processing? I have tried various solutions available on forums but nothing works for me. Here is what i want to accomplish:
// Create a document by supplying the filepath.
WordprocessingDocument wordDocument = WordprocessingDocument.Create("E:/Test/Executive.Docx", WordprocessingDocumentType.Document);
// Add a main document part.
MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();
// Create the document structure and add some text.
mainPart.Document = new Document();
Body body = mainPart.Document.AppendChild(new Body());
Paragraph para = body.AppendChild(new Paragraph());
Run run = para.AppendChild(new Run());
run.AppendChild(new Text("Executive Summary"));
if (para.Elements<ParagraphProperties>().Count() == 0)
para.PrependChild<ParagraphProperties>(new ParagraphProperties());
// Get the ParagraphProperties element of the paragraph.
ParagraphProperties pPr = para.Elements<ParagraphProperties>().First();
// Set the value of ParagraphStyleId to "Heading3".
pPr.ParagraphStyleId = new ParagraphStyleId() { Val = "Heading1" };
Your technique would totally work if you were editing an existing document. The problem is that a fresh document doesn't have a "Heading 1" predefined. You'd have to add it. So you have two choices:
1. Work with an existing template document
Create a template document (TemplatePath) to use as a base. In the code, copy it to the final destination (FinalPath) and add text/whatever to it, applying styles. Heading 1 will already be in the template.
if (File.Exists(FinalPath))
File.Delete(FinalPath);
File.Copy(TemplatePath, FinalPath);
WordprocessingDocument wordDocument = WordprocessingDocument.Open(FinalPath, true);
Paragraph para = body.AppendChild(new Paragraph());
Run run = para.AppendChild(new Run());
run.AppendChild(new Text("Executive Summary"));
para.ParagraphProperties = new ParagraphProperties(new ParagraphStyleId() { Val="Heading1" });
2. Create your new document from scratch
If you do this, it will have no built-in styles. So create a style, call it "Heading 1" and apply it to your paragraph.
WordprocessingDocument wordDocument = WordprocessingDocument.Create(FinalPath, WordprocessingDocumentType.Document);
MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();
mainPart.Document = new Document();
Body body = mainPart.Document.AppendChild(new Body());
Paragraph para = body.AppendChild(new Paragraph());
Run run = para.AppendChild(new Run());
run.AppendChild(new Text("Executive Summary"));
StyleDefinitionPart styleDefinitionsPart = wordDocument.AddStylesDefinitionPart();
Styles styles = styleDefinitionsPart.Styles;
Style style = new Style() {
Type = StyleValues.Paragraph,
StyleId = styleid,
CustomStyle = true
};
StyleName styleName1 = new StyleName() { Val = "Heading1" };
style.Append(styleName1);
StyleRunProperties styleRunProperties1 = new StyleRunProperties();
styleRunProperties1.Append(new Bold);
styleRunProperties1.Append(new Italic());
styleRunProperties1.Append(new RunFonts() { Ascii = "Lucida Console" };);
styleRunProperties1.Append(new FontSize() { Val = "24" }); // Sizes are in half-points. Oy!
style.Append(styleRunProperties1);
styles.Append(style);
pPr.ParagraphStyleId = new ParagraphStyleId(){ Val = "Heading1" };
para.PrependChild<ParagraphProperties>(new ParagraphProperties());
<sarcasm>See? OpenXML is a piece of cake!</sarcasm> I swear, my eyes are rolling so hard I'm getting a headache.
