Syntax Highlighting
ExpressionEditor supports syntax highlighting to visually distinguish functions and fields within expressions. Color-coded display improves readability and helps differentiate expression elements. The SyntaxHighlighting property of the C1ExpressionEditor class controls whether syntax highlighting is enabled.
Note: Operators and constants are not highlighted.
