Importing Documents

Our HTML Editor allows you to import documents or export its contents using RTF, Office Open XML, MIME HTML and Text file formats. And yes, optimized pasting options for Word documents are also available.


Ribbon vs Standard Toolbar

Whether you prefer to interact with the Editor via a Microsoft-Word inspired Ribbon or if you prefer the simplicity of a traditional toolbar, we've got you covered.


HTML Editing & Formatting

Incorporate HTML editing into your Web app.

The DevExpress ASP.NET HTML Editor allows users to modify HTML content/documents via a WYSIWYG HTML editor or in code and preview the result within its integrated HTML preview pane. Our HTML Editor supports automatic two-way synchronization between its visual HTML Editor and HTML Code Viewer. End-users can switch to the Code View and edit documents or can switch back and forth to use the view that best suits their editing requirements.

Advanced options include:

  • Intellisense and Code Highlighting
  • HTML Validation

Ribbon. Toolbars. Menu

Office-inspired interfaces your way.

With unmatched design/runtime options, our ASP.NET HTML Editor with its integrated Toolbar/Ribbon UI allows you to emulate the Microsoft Office end-user experience within your Web project with absolute ease.

Our HTML Editor was designed with flexibility in mind. Among its many features is its ability to fine-tune toolbar commands based on your specific business needs. You can use our default Toolbar commands, modify them as necessary or create Custom Toolbars and populate them with both standard and custom commands. As you might expect, you can also control availability of commands within a Toolbar based on context or in response to selection changes within your web app.

With a single option, you can substitute the browser's default Popup (Context) Menu with our ASP.NET HTML Editor's built-in menu.

Additional Info

Customizable ASP.NET Themes

The DevExpress ASP.NET Subscription ships with 20+ highly polished themes for your next web application. You can use each of these themes easily, without modification or manipulate them using our free ASP.NET Theme Builder application. See Demo

Sec 508 and Accessibility

The DevExpress ASP.NET Subscription makes it easy to create web applications that meet government regulations regarding web accessibility. Sec 508 and Web Content Accessibility Guidelines 1.0 support is available across our entire DevExpress ASP.NET Product Line. Read about accessibility

Touch and Mobile Device Enabled

Deliver elegant, touch-enabled ASP.NET and MVC web applications using the platform you know and love. The ASP.NET Subscription helps you leverage your current investments and address customer needs via a comprehensive range of Web Forms Controls and MVC Extensions that support touch on iOS Safari, Android and Internet Explorer 10.

AJAX Enabled with Rich Client-Side API

Each and every control provides an ability to update the control using callbacks, eliminating the need to re-load the entire page. This callback functionality allows you to optimize how data is transferred to the client. We also offer you a comprehensive client-side API, along with the ability to handle events on the client side. With our ASP.NET components, you have full control over the control's behavior via client functions.

Fast and Lightweight with XHTML Compliance

DevExpress controls are optimized for exceptional performance and efficient memory use without the loss of functionality or features. DevExpress ASP.NET controls also support optimizations like HTML compression, callbacks, image sprites, resource caching and sharing. Key ASP.NET controls in this subscription use semantic HTML to keep output clean and minimal. The semantic HTML markup means that web pages are lighter and faster, more search engine friendly and provide improved accessibility for screen readers.

Straightforward Localization

All DevExpress ASP.NET AJAX Controls can be easily localized using satellite resource assemblies. DevExpress delivers satellite assemblies for a large variety of languages and cultures. To make it easy to get started, resource files for four cultures are included to our installation: German, Japanese, Russian, and Spanish. If you need to modify our shipping resources or create satellite assemblies for a different language, simply use our Online Localization Service, a free tool for our active ASP.NET subscribers.
