Syntax Highlighting in a ListBox

Question

Hi all,

I've searched the web and I can't seem to find anything that will work for me. I've seen plenty of discussion, and even some fairly extensible open-source tools, for code editors that provide line numbers and syntax highlighting.

Here's my dilemma...

I'm working on a "digital code review" project in C#.NET that allows users to specify source files, add them to a particular session, and other users can make comments and line references to the files being reviewed.

Basic requirements:

• Must be written in C#.NET
• I don't need to be able to edit the text in the text box
• Users need to be able to select a line (or multiple lines), to make line references.

It seems to me that I need some fancy implementation of a ListBox control (not a drop-down list) that has some OwnerDraw capabilities to add line numbers and syntax highlighting. Unfortunately, I haven't had any luck putting it together myself, and I can't seem to find a control that's already been written or a reference on how I might be able to accomplish this.

Any suggestions??

Answer 1

I suggest to try ScintillaNet. It has syntax highlight and line numbers (and so much more). However you cannot select more lines only one selection at the time.

Answer 2

I would use a text box control for this, just make it read only and put the line numbers in when you load it. Just a quick question, when you say:

Users need to be able to select a line (or multiple lines), to make line references.

Is this in a web app? How do the users indicate that they want to create a reference (some button somewhere?). Easier to do on windows with a context menu. Where does the user reference to the code go, how does it appear to other users viewing the code?
