The WinForms Syntax Editor control is a powerful text editor control similar to the Microsoft Visual Studio editor. It provides a built-in syntax highlighting and code editing experience for popular languages and allows users to create custom syntax highlighting of keywords and operators for their own language. It offers all the essential features end users expect: syntax highlighting, editing, undo, redo, cut, copy, paste, IntelliSense, error validation, line numbering, highlighting modified lines, custom language configuration. It supports context choice, context tooltip, single line mode, multi-tasking with split view, word wrap, printing, and export options.
This control provides syntax highlighting for programming, scripting, and markup languages. It also allows users to customize built-in languages.
The Syntax Editor control offers built-in syntax highlighting and code editing experiences for the following languages:
Create custom syntax highlighting of keywords and operators of your own language.
IntelliSense displays a pop-up with a list of code completion options to speed up coding by reducing typos and other common mistakes.
Display helpful pop-up hints about alternate syntax for invoking what is being typed and its parameters. Choose your invocation overload with the Up arrow and Down arrow keys or by clicking the arrow buttons in the pop-up.
Built-in interactive tooltips appear automatically when the pointer is placed over a collapsed block of text.
Display code blocks in a tree structure and expand and collapse the code blocks interactively for readability. WinForms Syntax Editor automatically chooses where to create outlines for built-in languages. Users can create outlining for their own syntax highlighting.
Comment or uncomment code with the help of the comment option. Users can select the required block of code to comment. WinForms Syntax Editor comments the current line when there is no selection.
Display markers at the start of lines modified after the file is loaded or after the last file save operation.
Included is keyboard and context menu support for undo and redo operations that erase the last change in a document and reinsert it.
Use the keyboard or context menu for clipboard operations such as cut, copy, and paste.
WinForms Syntax Editor supports rectangular block selection to select lines from specific columns, like in Visual Studio, plus normal selection.
Indentation support helps format source code to improve readability.

Shortcut keys can be used for all editing and navigation operations. A built-in window is available for modifying the key mapping of shortcut operations.
Display a single document in several views with horizontal and vertical orientations, allowing users to work on different areas of a document at the same time.
Make the Syntax Editor a simple text box with syntax highlighting, editing, and clipboard operations.
Use the WinForms Syntax Editor as a viewer control in order to view files and restrict code editing.
Customize the appearance of the text color in a specific range of lines.
Display a thin vertical strip that enables users to select the contents of the entire line.
