Examples

Shows advances ways of customizing list labels.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// A list allows us to organize and decorate sets of paragraphs with prefix symbols and indents.
// We can create nested lists by increasing the indent level. 
// We can begin and end a list by using a document builder's "ListFormat" property. 
// Each paragraph that we add between a list's start and the end will become an item in the list.
List list = doc.Lists.Add(ListTemplate.NumberDefault);

// Level 1 labels will be formatted according to the "Heading 1" paragraph style and will have a prefix.
// These will look like "Appendix A", "Appendix B"...

list.ListLevels[0].LinkedStyle = doc.Styles["Heading 1"];

// Level 2 labels will display the current numbers of the first and the second list levels and have leading zeroes.
// If the first list level is at 1, then the list labels from these will look like "Section (1.01)", "Section (1.02)"...
list.ListLevels[1].NumberFormat = "Section (\x0000.\x0001)";
list.ListLevels[1].NumberStyle = NumberStyle.LeadingZero;

// Note that the higher-level uses UppercaseLetter numbering.
// We can set the "IsLegal" property to use Arabic numbers for the higher list levels.
