Actipro SyntaxEditor


Editing control similar to a multi-line TextBox that highlights text and provides features for code editing and is similar to the code editor in Microsoft Visual Studio.

SyntaxEditor is a powerful text editing control that is packed with features for efficient code editing, including syntax highlighting, code outlining, parsing, line numbers, block selection, IntelliPrompt UI, zooming, adornments, single-line mode and much more. It is built on top of our next-generation extensible text/parsing framework and has many of the same code editing features found in the Visual Studio code editor.

SyntaxEditor is designed for use in online IDE (integrated development environment) applications, however there are many other applications out there than can take advantage of such a control. Over 20 sample languages are included to get you started (such as C#, HTML, Javascript and more) and optional premium add-ons with advanced functionality for editing C#, VB, Python, XML, JavaScript and JSON are available as well.
