The Rich Text Format (RTF) is a convenient standard for rich text editing that prevents users from needing Microsoft Word or some other expensive word processing application. The .NET RichTextBox offers developers a way to provide rich edit capabilities in their applications without purchasing third-party tools or writing volumes of code.
Developers that have worked extensively with RTF know that codes used within it are numerous and sometimes cumbersome to work with. The RichTextExplorer application uses the .NET RichTextBox and few lines of code to show the corresponding RTF behind any text entered, and also allows you to edit the RTF directly and see how it effects the rendered text.
