Inherits NumberingListBase
The following members return NumberingList objects:
The NumberingList object is based on an abstract numbering definition which can be accessed via the NumberingList.AbstractNumberingList property.
Document paragraphs are included into a numbering list by using the ParagraphCollection.AddParagraphsToList method.
The list to which a specific paragraph belongs can be obtained via the Paragraph.ListIndex property.
For an example of use see the AbstractNumberingList article.
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();
