Hello Deri,

Thank you for contacting us.

In this ListStyle documentation you can find description on how to build custom list appearance. Basically, the numbering representation depends on ListLevelStyle NumberingFormat and LevelText properties. Using UpperLetter numbering format and appropriate level text you may make numbers appear as "AAA", "BBB", "CCC". However, there is no numbering format allowing you to convert numbers to the words "ONE", "TWO", "THREE". With the following code, you may create custom list style and build document similar to the attached screenshot:

RadDocument document = this.radRichTextBox.Document;

RadDocumentEditor editor = new RadDocumentEditor(document);

ListStyle listStyle = new ListStyle();

for (int i = 0; i < 9; i++)

{

bool isEven = (i & 1) == 0;

ListLevelStyle listLevel = new ListLevelStyle();

listLevel.StartingIndex = 1;

listLevel.NumberingFormat = isEven ? ListNumberingFormat.UpperLetter : ListNumberingFormat.Decimal;

listLevel.Indent = 48 + (24 * i);

listLevel.LevelText = isEven ? string.Format("{0}{1}{2}{0}{1}{2}{0}{1}{2} DOT ", '{', i, '}') : string.Format("{0}{1}{2} DOT ", '{', i, '}');

listLevel.FontWeight = FontWeights.Bold;

listStyle.Levels.Add(listLevel);

}

editor.ChangeParagraphListStyle(listStyle);

editor.ChangeParagraphListLevel(0);

editor.Insert("First level first item");

editor.InsertParagraph();

editor.ChangeParagraphListLevel(1);

editor.Insert("Second level first item");

editor.InsertParagraph();

editor.Insert("Second level second item");

editor.InsertParagraph();

editor.ChangeParagraphListLevel(2);

editor.Insert("Third level first item");

editor.InsertParagraph();

editor.ChangeParagraphListLevel(1);

editor.Insert("Second level third item");

editor.InsertParagraph();

editor.ChangeParagraphListLevel(0);

editor.Insert("First level second item");

editor.InsertParagraph();

editor.ChangeParagraphListStyle(null);

editor.Insert("Some text outside the list.");

I hope this is helpful. If you have any other questions or concerns please do not hesitate to contact us again.
