# Editor for WinForms Overview

Get started with C1Editor that uses XHTML as its basic format (instead of RTF or proprietary formats) and makes it extremely easy to automate all kinds of document handling tasks.

## Content

Load, save, and edit your XHTML documents with **Editor for WinForms**. Choose from a WYSIWYG **Design** mode, **Source** mode, or **Preview** mode to edit or view your documents. The [C1Editor](/componentone/api/win/online-richtexteditor/dotnet-framework-api/C1.Win.C1Editor.4.8/C1.Win.C1Editor.C1Editor.html) control is bound to the XHTML document, so you can make changes directly to your XHTML document from within the control. Editing XHTML documents has never been so easy!
