OpenXML 2 SDK - Word document - Create bulleted list programmatically - ms-word

Question

Using the OpenXML SDK, 2.0 CTP, I am trying to programmatically create a Word document. In my document I have to insert a bulleted list, an some of the elements of the list must be underlined. How can I do this?

Answer 1

Lists in OpenXML are a little confusing.
There is a NumberingDefinitionsPart that describes all of the lists in the document. It contains information on how the lists should appear (bulleted, numbered, etc.) and also assigns and ID to each one.
Then in the MainDocumentPart, for every item in the list you want to create, you add a new paragraph and assign the ID of the list you want to that paragraph.
So to create a bullet list such as:
Hello,
world!
You would first have to create a NumberingDefinitionsPart:
NumberingDefinitionsPart numberingPart =
mainDocumentPart.AddNewPart<NumberingDefinitionsPart>("someUniqueIdHere");
Numbering element =
new Numbering(
new AbstractNum(
new Level(
new NumberingFormat() { Val = NumberFormatValues.Bullet },
new LevelText() { Val = "·" }
) { LevelIndex = 0 }
) { AbstractNumberId = 1 },
new NumberingInstance(
new AbstractNumId() { Val = 1 }
) { NumberID = 1 });
element.Save(numberingPart);
Then you create the MainDocumentPart as you normally would, except in the paragraph properties, assign the numbering ID:
MainDocumentPart mainDocumentPart =
package.AddMainDocumentPart();
Document element =
new Document(
new Body(
new Paragraph(
new ParagraphProperties(
new NumberingProperties(
new NumberingLevelReference() { Val = 0 },
new NumberingId() { Val = 1 })),
new Run(
new RunProperties(),
new Text("Hello, ") { Space = "preserve" })),
new Paragraph(
new ParagraphProperties(
new NumberingProperties(
new NumberingLevelReference() { Val = 0 },
new NumberingId() { Val = 1 })),
new Run(
new RunProperties(),
new Text("world!") { Space = "preserve" }))));
element.Save(mainDocumentPart);
There is a better explanation of the options available in the OpenXML reference guide in Section 2.9.

Answer 2

I wanted something that would allow me to add more than one bullet list to a document. After banging my head against my desk for a while, I managed to combine a bunch of different posts and examine my document with the Open XML SDK 2.0 Productity Tool and figured some stuff out. The document it produces now passes validation for by version 2.0 and 2.5 of the SDK Productivity tool.
Here is the code; hopefully it saves someone some time and aggravation.
Usage:
const string fileToCreate = "C:\\temp\\bulletTest.docx";
if (File.Exists(fileToCreate))
File.Delete(fileToCreate);
var writer = new SimpleDocumentWriter();
List<string> fruitList = new List<string>() { "Apple", "Banana", "Carrot"};
writer.AddBulletList(fruitList);
writer.AddParagraph("This is a spacing paragraph 1.");
List<string> animalList = new List<string>() { "Dog", "Cat", "Bear" };
writer.AddBulletList(animalList);
writer.AddParagraph("This is a spacing paragraph 2.");
List<string> stuffList = new List<string>() { "Ball", "Wallet", "Phone" };
writer.AddBulletList(stuffList);
writer.AddParagraph("Done.");
writer.SaveToFile(fileToCreate);

Adam's answer above is correct except it is new NumberingInstance( instead of new Num( as noted in a comment.
Additionally, if you have multiple lists, you should have multiple Numbering elements (each with it's own id eg 1, 2, 3 etc -- one for each list in the document. This doesn't seem to be a problem with bullet lists, but numbered lists will continue using the same numbering sequence (as opposed to starting over again at 1) because it will think that it's the same list. The NumberingId has to be referenced in your paragraph like this:
ParagraphProperties paragraphProperties1 = new ParagraphProperties();
ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "ListParagraph" };
NumberingProperties numberingProperties1 = new NumberingProperties();
NumberingLevelReference numberingLevelReference1 = new NumberingLevelReference() { Val = 0 };
NumberingId numberingId1 = new NumberingId(){ Val = 1 }; //Val is 1, 2, 3 etc based on your numberingid in your numbering element
numberingProperties1.Append(numberingLevelReference1);
numberingProperties1.Append(numberingId1);
paragraphProperties1.Append(paragraphStyleId1);
paragraphProperties1.Append(numberingProperties1);
Children of the Level element will have an effect on the type of bullet, and the indentation.
My bullets were too small until I added this to the Level element:
new NumberingSymbolRunProperties(
new RunFonts() { Hint = FontTypeHintValues.Default, Ascii = "Symbol", HighAnsi = "Symbol" })
Indentation was a problem until I added this element to the Level element as well:
new PreviousParagraphProperties(
new Indentation() { Left = "864", Hanging = "360" })

Answer 4

And if you are like me - creating a document from a template, then you may want to use this code, to handle both situations - when your template does or does not contain any numbering definitions:
// Introduce bulleted numbering in case it will be needed at some point
NumberingDefinitionsPart numberingPart = document.MainDocumentPart.NumberingDefinitionsPart;
if (numberingPart == null)
{
numberingPart = document.MainDocumentPart.AddNewPart<NumberingDefinitionsPart>("NumberingDefinitionsPart001");
}

Answer 5

Not sure if this helps anyone, but here is my snippet for inserting a list of bullets.
Create the word processing document and word document body
WordprocessingDocument wordprocessingDocument = WordprocessingDocument.Open($"{tempFolder}{tempFileName}", true);
Body wordDocumentBody = wordprocessingDocument.MainDocumentPart.Document.Body;
Then get the insert index. This is placeholder text inside the word document, so you can insert into the correct place in the word document.
int insertIndex = wordDocumentBody.ToList().IndexOf(wordDocumentBody.Where(p => p.InnerText.Contains("PLACEHOLDER_TEXT")).First());
You can then call this method to insert into the word document in both bullet points for lettering.
public static void InsertBullets(Body wordDocumentBody, int insertIndex, int bulletStyle, List<string> strToAdd)
{
//// Bullet Styles:
// 1 - Standard bullet
// 2 - Numbered
foreach (string item in strToAdd)
{
Paragraph para = wordDocumentBody.InsertAt(new Paragraph(), insertIndex);
ParagraphProperties paragraphProperties = new ParagraphProperties();
paragraphProperties.Append(new ParagraphStyleId() { Val = "ListParagraph" });
paragraphProperties.Append(new NumberingProperties(
new NumberingLevelReference() { Val = 0 },
new NumberingId() { Val = bulletStyle }));
para.Append(paragraphProperties);
para.Append(new Run(
new RunProperties(
new RunStyle() { Val = "ListParagraph" },
new NoProof()),
new Text($"{item}")));
insertIndex++;
}
}
You can then remove the placeholder text after with this.
wordDocumentBody.Elements().ElementAt(wordDocumentBody.ToList().IndexOf(wordDocumentBody.Where(p => p.InnerText.Contains("PLACEHOLDER_TEXT")).First())).Remove();
