Manish, I do not know if you have been able to resolve this issue or not, but as I am having a similar problem I wanted to add on. In my case I have been able to format my desired text into bulleted list items - however, I cannot seem to get them to appear WHERE I want them to be. Using richTextBox.Insert will put the inserted text to the beginning of the document (or rather, after other inserted items prior).
In my case, what I need is to have the items inserted into the current section of the document that I am working in - which I am not able to do so far.
Either way - here is the code that I used to insert the bulleted list:
Section section =
Paragraph titleParagraph =
Span titleSpan =
"Current Status Highlights / Executive Summary"
Span span2 =
Span span3 =
"Wins and Updates:"
"Issues and Risks:"
DocumentTextSearch search =
TextRange range = search.Find(span2.Text);
TextRange range2 = search.Find(span3.Text);
&& range2 !=
