A footnote looks like a number (numbering type is specified in TRVStyle.FootnoteNumbering). If FormatString is defined, a number is displayed formatted according to this string (for example, if FormatString is a single character, the footnote displays a single character).
Footnote contains a subdocument. This subdocument is not displayed in TCustomRichView where the footnote is inserted, but it can be printed using TRVPrint. Subdocuments for all footnotes are printed at the bottom of page where this footnote occurs. TRichView cannot print text for a footnote on several pages.
The TRVReportHelper component doesn't display documents of footnotes. If you need to draw a document with footnotes on a given canvas, use TRVPrint in virtual printer mode.
ScaleRichView note: TSRichViewEdit displays and allows editing footnotes.
Class for this item type is TRVFootnoteItemInfo (see for detailed information).
Style of this item type: rvsFootnote (-203)

Properties
Footnotes have all properties of numbered sequences.
Differences:
▪NumberType is read-only; it always returns TRVStyle.FootnoteNumbering;
▪SeqName = '@footnote@' and must not be changed.
All footnotes can be numbered sequentially, or numbering can be reset on each page, depending on the value of FootnotePageReset property of the linked TRVStyle component.
Saving and Loading
Export to HTML
Subdocuments for all footnotes are saved after the main document. Before each subdocument, <a name="footnoteN"></a> is inserted, where N is an index of this footnote (in the list of all numbered sequences and notes). Footnotes are saved as hyperlinks to this anchor.
RTF and DocX
Footnotes can be exported in RTF and DocX. If FormatString contains a single character, it can be exported to RTF/DocX.
You can set RTFReadProperties.IgnoreNotes to True, and footnotes will not be imported from RTF/DocX.
Markdown
Markdown
Footnotes are saved as footnotes if the footnote format extension is active (the rvmdeFootnotes is included in TRichView.MarkdownProperties.Extensions), and the rvntFootnote is included in TRichView.MarkdownProperties.NotesSavedAsFootnotes.
Otherwise, the note document is saved at the note insertion point within square brackets.
If the table format extension is active, notes in table cells cannot be saved.
Text
When copying or saving a selected text, footnotes are not included in text. When saving the whole text, they are saved inside [], for example:
This is a text [1 sequence of characters] to show footnotes
[2 note of text placed at the bottom of a page].
