RichTextEditor Features

The leading WYSIWYG, browser-based, XHTML/HTML editor lets content contributors easily create and publish Web content, while developers maintain control over a site's look and feel.

Thousands of companies have integrated Rich Text Editor into content management systems, e-learning, discussion forums, Web e-mail, and other applications. Plus, Rich Text Editor allows developers to easily customize and extend the editor.


A cross-browser, cross-platform WYSIWYG Editor
Following 9 year old tradition of industry #1 cross-browser support, RichTextEditor continues to offer even better quality and compatibility by supporting all major browsers: IE 6.0+, Firefox 2.0+, Mozilla 1.3+, Safari (1.3+), Opera 9.0, IE 10 and Chrome. This includes Macintosh and Linux.
Generates clean XHTML. Compliant with the web standards, no deprecated tags
Most WYSIWYG editors are just JavaScript wrappers around the editing control built into browsers such as the MSHTML control found in IE. These types of editor (which generate HTML and then run code clean-up routines against it) have significant limitations. By contrast, RichTextEditor is built from the ground up to be a true XHTML editor in its own right.
Extremely small and fast
Most feature-rich WYSIWYG editors suffer long loading times due to large javascript files. RichTextEditor only loads the necessaery scripts to client browsers. Numerous optimization methods have been applied. It's clean, compact, extremely fast-loading, but still powerful and efficient.
Insert clean HTML from Microsoft Word
When text is pasted from Microsoft Word a lot of unnecessary word specific markup is carried across. This can result in web pages that take an unnecessarily long time to download. The Paste from Word button solves this by removing word markup before pasting the text into your web page.
Advanced file upload function
We integrate a hi-performance ASP.NET upload component - Ajax uploader into Rich Text Editor. Ajax Uploader allows you to select and upload multiple files at once. It also supports client side validation of the file size/type before uploading.
Format Painter
The Format Painter takes the formatting from one piece of text and pastes it onto content you select. This is handy when you have a combination of formats on something, like a size, color and style, and want to apply them to another item, without having to apply them individually.
HTML5 Support
HTML5 will be the new standard for HTML. Major browsers support many of the new HTML5 elements and APIs. RichTextEditor is providing support for various HTML5 elements, attributes, and values.
Show Rulers
RichTextEditor can display rulers, one along the top and one along the left side of the editor window. Rulers allow you easiluy align text, graphics, tables, and other elements in a document.
Quick Style
RichTextEditor 8.0 has a fast and easy way to save a new style. Say you spent some time formatting text just the way you want it and you want to save that format as a style so you can use it again in your current document.
Code Cleaner
You can automatically remove empty tags, combine nested span tags, and otherwise improve messy or unreadable HTML or XHTML code.
Easy-to-use interface
RichTextEditor's streamlined toolbar is a refreshing alternative to the dizzy array of toolbar buttons/controls seen in most WYSIWYG editors. RichTextEditor is able to offer more functionalities with a tighter toolbar while advanced functionalities are also available.
Indenting text the "right" way
Most editors use <blockquote> for indenting which is wrong. Rich Text Editor encourages the correct use of <blockquote> for quotations only, and uses CSS for indenting.
AJAX Support
Rich Text Editor gives you the ability to update control content using callbacks - thus eliminating the need to re-load the entire page.
Inserts custom tags as placeholders
Rich Text Editor makes it easy for business users to add semantic meaning to text and objects by inserting custom tags that can be used as placeholders for dynamic content.
Support accessibility according to W3C WAI and section 508 accessibility guidelines.
Rich Text Editor optional accessibility settings ensure your site complies with Section 508, so people with disabilities can have full access to your content.

Multi-language support (Demo)
All labels, buttons, tooltips and messages are located in external javascript language files, so that the language of the editor can be switched with a single property. You can also create a new language in a matter of minutes.

Use MaxHTMLLength or MaxTextLength to Protect Your Database (Demo)
If you tried to insert a record whose text length is greater than allowed by your table, an error will be reported. To prevent this type of error from occurring, developers can use MaxHTMLLength or MaxTextLength in the Rich Text Editor to limit the length of the user's input.
Apply security to control user access to resources

Rich Text Editor allows developers to assign a pre-defined set of permissions by group or individual. This prevents a normal user to access the administration functionality.

The details of permissions are specified by an XML security policy file. Each level maps to a specific file. The default mappings:

  • admin - maps to admin.config
  • default - maps to default.config
  • guest - maps to guest.config

You can customize and extend each policy file by editing the XML security policy file. You can also create your own policy files that define arbitrary permission sets.
