Hello, I have a problem.
What I need is to highlight multiple matches within some portion of text as the user types a search pattern. Right now I'm using a RichTextBox to highlight text. The highlighting takes place if a user changes the search pattern and naturally it happens with each key press. It works, but I'm experiencing a performance issues. If the text is large enough the highlighting takes too long (up to several seconds).
Facing that I tried to launch the highlighting procedure in a different thread aborting it and launching it again if the search pattern was changed during the highlighting but still I'm not satisfied with performance.
Now I'm asking if there some other control I could use to speed up the process?
