Examples

Shows how to insert a TOC, and populate it with entries based on heading styles.

    builder.StartBookmark("MyBookmark");

    // Insert a TOC field, which will compile all headings into a table of contents.
    // For each heading, this field will create a line with the text in that heading style to the left,
    // and the page the heading appears on to the right.
    FieldToc field = (FieldToc)builder.InsertField(FieldType.FieldTOC, true);

    // Use the BookmarkName property to only list headings
    // that appear within the bounds of a bookmark with the "MyBookmark" name.
    field.BookmarkName = "MyBookmark";

    // Text with a built-in heading style, such as "Heading 1", applied to it will count as a heading.
    // We can name additional styles to be picked up as headings by the TOC in this property and their TOC levels.
    field.CustomStyles = "Quote; 6; Intense Quote; 7";

    // By default, Styles/TOC levels are separated in the CustomStyles property by a comma,
    // but we can set a custom delimiter in this property.
