• Import any HTML document. Any HTML document can be imported. Internet Explorer may alter the HTML slightly, but presentation is rarely affected in any way.

Miscellaneous

• Broad image support. Support for drag-and-drop image insertion and image upload.
• No JavaScript experience required. Normally to use an editor like this you would need to write hundreds of lines of HTML and JavaScript. With RichTextBox you do not need to write a single line of client-side script.
• Auto-sizing. Creates the optimum editable width for users. but if you need to, you can fix the size.
• Use anywhere. RichTextBox works from within pages, user controls, and other server controls.
• Focus control. The Focus property allows you to specify whether or not the editor takes focus when the page loads.
• Straightforward licensing. All licensing is per-hostname or per-server. There are no per-user costs.
• Relative URLs. The editing functionality in Internet Explorer by default stores all URLs as absolute URLs. In this version the editor overrides this functionality and ensures that all URLs in the current document that reference an absolute URL to the current host are efficiently stripped back to relative URLs when you submit the page to the server. If this is not what you need you can disable it using HtmlOutputChangeAbsoluteURLsToRelative property.
• Multi-cultural. The names of all the menus and the names of the buttons can be changed, as can all warning messages. RichTextBox will work in any culture or language, including Asian cultures, and supports UNICODE.

• Extensible. You can subclass RichTextBox to create custom versions.
• HTML-mode styling. Apply a cascading stylesheet to the editor when in HTML mode. e.g. a proportional font like Courier New.

• Visible/invisible. Hide/show the RichTextBox easily, from your code.
• Modal dialogs. RichTextBox supports client-side modal dialog boxes.
• SSL / HTTPS. RichTextBox fully supports Secure Sockets Layer and can be used on secure web servers.
