The DiffViewer control displays multi-line text with optional visual diff highlighting. It is especially useful for showing code changes, configuration differences, or version comparisons.

 

Each line is passed through the Lines property. If a line begins with a + or -, it is rendered in a special style to indicate additions and deletions respectively:

 

•Lines starting with + are highlighted in blue and bolded.

•Lines starting with - are highlighted in red and struck through.

 

Other lines are rendered as plain text.

 

Syntax:

 

DiffViewer[:Name]

 Lines: [array of lines]

 

•Name – optional ID to reference in logic.

•Lines – array of strings; each string represents a line.

 

Properties:

 

•Lines – a string array property containing the lines to be displayed. This property supports diff-like prefixes (+, -).
