Expanded grid - formatted strings?

I am trying to get the data returned as a string to be formatted. Just simple stuff like this:

String msg = "My Message";
msg = msg + Environment.NewLine + "New Line";

Should display like:

My Message
New Line

Even the embedded "/n/r" does nothing. Is this supported or is there another way?
You need to assume I don't know the formatting at design time.

Thanks,
Orlando

Thank you for the quick response, that worked perfectly.
