Features

Familiar Text Editing

Enable users to enter and modify text in an interface they are used to. With intuitive toolbox controls they will feel right at home.

Spell Checking

The built-in spell checker allows for the user to check their text for spelling mistakes. With the ability to add your own words, or even create a custom dictionary, you can rest assured that all the content will be properly spell checked.

Paste from Word

Pasting and editing content from word has never been easier. With the ability to paste the content as is, strip out certain Word formatting, or even just plain text, you have full control over what content gets pasted into the Editor.

RibbonBar Integration

Provide your users with an editor interface they are already used in Word by integrating the RibbonBar controls as the toolbar for the editor. Group menu items such as copy and paste into their own tabs for an even further customized experience.

Rich Client-side API

Modify or interact directly with the Editor on the client thanks to the rich client-side API. Execute any of the built-in, as well as custom, toolbox commands and even interact with the content.

Localization and Accessibility

Create a custom version of the Editor for any language desired and maintain a high level of accessibility. Allow the user to switch, on-the-fly, to another language and easily create additional localized versions of the Editor, all while being reassured that users with disabilities can access the features.
