How to define special syntax for the editor

Hello,

First, for the tags, do you want them to all be one color or do you want the delimiters (<. >) to be separate colors?  If you make them separate, then they will be three tokens instead of one.

Thank you for your help, I guess the color groups are:

Text strings have color 1

<> have color 2

[ ] have color 3

I will also need to color words with color 4 while search and find

I also may need to be able to programatically open a list of choices at any point (similar to spell checking but not only for spell checking).

That should do it as a starting point.

Is this something the control can support?

Thank you.

Yes, you can make a lexical parser to tokenize the text however you want.  So strings can be one token, <...> ranges can be another token, and [ and ] character can be tokens too.  Each token kind can be assigned to use a specific highlighting style.  That's how syntax highlighting works.  Take a look at our dynamic lexer examples to see how we built pattern-based lexical parsers for various common languages.

You can even drive code outlining with tokens if you like.

For coloring words while searching, you could possibly do that with span indicators (see the indicators sample).

And we support IntelliPrompt member lists for picking options to replace text with, similar to the Intellisense in Visual Studio.

You can start looking at the samples and documentation to make sure everything is working for your needs.  They show off most of the features.
