UI Experience

The ASPxRichEdit provides a UI experience similar to that of Microsoft Word.

Ribbon UI

The ASPxRichEdit's UI experience includes full integration with the DevExpress ASP.NET Ribbon control. The ASPxRichEdit can use either a built-in ribbon or an external ribbon control as a toolbar. A ribbon can be automatically populated with the default ribbon tabs. Or, you can manually customize the ribbon based on your application needs.

Run Demo: Ribbon Customization

Advanced Context Menus and Built-in Dialogs

The ASPxRichEdit provides several context menus allowing you to quickly perform actions linked to specific elements. Specially designed built-in dialogs help you work with documents and modify different document element settings.

Run Demo: Load/Save

UI for Printing
An integrated UI allows end-users to customize document print settings and print document content as needed.
Horizontal Ruler
The horizontal ruler controls the width of text columns, and the horizontal spacing of paragraph margins and tabs.
Status Bar
A status bar is displayed at the bottom of the editor providing helpful feedback to end-users (e.g., when the editor sends callbacks to the server).
Fullscreen Mode
The DevExpress ASPxRichEdit can be maximized to occupy the browser's entire client region. You can show dialogs under an external ribbon in Fullscreen mode.

Developer API

Server-Side API
You can modify a document on the server side with a non-visual cross-platform .NET library Office File API.
Client-Side API

The Rich Text Editor provides a comprehensive client API, allowing you to manipulate the open document programmatically on the client side.
