I have a RichTextBox control. I use it for syntax highlighting in my text.
The problem is: after a syntax is highlighted, when user press Ctrl+Z (calls Undo action)... control "unhighlights" my text.
For highlighting I use Select method and SelectionColor property. How to suppress writting actions into the undo stack of a RichTextBox during SelectionColor changes? Is it possible?work.
I tried using the LockCurrentUndoUnit method on the highlight logic to solve this problem, but it did not work.
