AbstractNumberingList Interface

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

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v20.2.Core.dll

Declaration

[ComVisible(true)]
public interface AbstractNumberingList :
    NumberingListBase

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.

Bulleted List

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();

Numbered List

Document document = server.Document;

document.BeginUpdate();

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

//Specify the list's type
abstractListNumberingRoman.NumberingType = NumberingType.Simple;

//Define the first level's properties
ListLevel level = abstractListNumberingRoman.Levels[0];
level.ParagraphProperties.LeftIndent = 150;

// Align list with the surrounding text
level.ParagraphProperties.FirstLineIndentType = ParagraphFirstLineIndent.Hanging;
level.ParagraphProperties.FirstLineIndent = 75;
level.Start = 1;

//Specify the roman format
level.NumberingFormat = NumberingFormat.LowerRoman;
level.DisplayFormatString = "{0}.";

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

document.EndUpdate();

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