AbstractNumberingList Interface

Serves as a pattern for numbered and bulleted lists to define their appearance.

Related API Members

The following members return AbstractNumberingList objects:

• AbstractNumberingListCollection.Add()
• AbstractNumberingListCollection.CreateNew()
• NumberingList.AbstractNumberingList
• TemplateAbstractNumberingList.CreateNew()

Remarks

You cannot use the AbstractNumberingList objects directly to apply numbering to paragraphs. The NumberingList instance is an actual list representation. Use the AbstractNumberingListCollection.Add method to create a list pattern. Use the NumberingListCollection.Add method with the index of the abstract numbering list as a parameter to create an actual list that can be applied to paragraphs.

The following code snippets illustrate how to create bulleted and numbered list.

Example: Create a Bulleted List

View Example

ListsActions.cs

Document document = server.Document;
document.BeginUpdate();

// Create a new list pattern object
AbstractNumberingList list = document.AbstractNumberingLists.Add();

//Specify the list's type
list.NumberingType = NumberingType.Bullet;
ListLevel level = list.Levels[0];

//Set the left indent of the list
level.ParagraphProperties.LeftIndent = 100;

//Specify the bullets' format
//Without this step, the list is considered as numbered
level.DisplayFormatString = "\u00B7";
level.CharacterProperties.FontName = "Symbol";

//Create a new list based on the specific pattern
NumberingList bulletedList = document.NumberingLists.Add(0);

// Add paragraphs to the list
ParagraphCollection paragraphs = document.Paragraphs;
paragraphs.AddParagraphsToList(document.Range, bulletedList, 0);

document.EndUpdate();

ListsActions.vb

Dim document As Document = server.Document

' Create a new list pattern objects

' Specify the list's type
list.NumberingType = NumberingType.Bullet
Dim level As ListLevel = list.Levels(0)

' Set the left indent of the list
level.ParagraphProperties.LeftIndent = 100

' Specify the bullet's format
' Without this step, the list is considered as numbered
level.DisplayFormatString = "·"
level.CharacterProperties.FontName = "Symbol"

' Create a new list based on the specific pattern
Dim bulletedList as NumberingList = document.NumberingLists.Add(0)

' Add paragraphs to the list
Dim paragraphs As ParagraphCollection = document.Paragraphs
paragraphs.AddParagraphsToList(document.Range, bulletedList, 0)
document.EndUpdate()
