how to assign tool-tip to my text in RadRichTextBox?

[Sopan]

Hi
Is there any way to assign tool-tip to text in RadRichTextBox.

I had tried by assigning Cross-reference bookmark by using editor.InsertBookmark(...) and editor.InsertCrossReferenceToBookmark(... , ... , ..) method. Bookmark is implemented but there is tool-tip is missing.

So how to enable tool-tip which normally shows in MS word.

Any alternate ways?
