Remarks

The Rich Edit supports only the formats that are listed in the ListLevelFormat enum. If you open a document that uses an unsupported list level format, the Rich Edit keeps that format, but displays it as Decimal.

Use the list’s ChangeLevelPropertiesAsync(Int32, Action<ListLevelProperties>, CancellationToken) method to change a list level’s number or bullet format.
