SyntaxEditor for WPF and Silverlight have the ability for you to fully customize the highlighting styles used to syntax highlight text. While the syntax highlighting is generally performed via the lexing of text, there also is a facility built into SyntaxEditor that allows you to tag other arbitrary ranges of text and apply a custom style to them.
Styles allow the text to change its color, background, bold, italics, underline, strike-through, font family, size, etc. In the upcoming 2012.1 version, we've added border rendering capabilities into the mix!
Highlighting Style Border Samples
Let's see some examples of how this looks. In each of these samples, we rendered the same code but applied a customized style over the word "ActiproTest".
The first sample shows a grey solid border that has rounded corners and a silver background.
The second sample shows a dotted dark blue border.
The third sample shows a dashed red border and light red background.
Note how syntax highlighting that comes from the language's lexer is still in effect. We are using a custom classification tagger to tag the "ActiproText" as special and needing to have a customized style. Its border merges seamlessly with the normal lexing features of SyntaxEditor.
This new feature will be in the 2012.1 versions of our WPF and Silverlight controls.
