Answer 1

I have added a FlowDocument to the RichTextBox and a Paragraph to the FlowDocument.

Sample code is:

Paragraph para = new Paragraph();
        FlowDocument fd = new FlowDocument();
        fd.Blocks.Add(para);
        txtExpression.Document = fd;
        para.Inlines.Add(new Button() { Content = "Hello!" });
