Is there a way to highlight a cell in TFlexCelPreviewer ? I cannot see anything obvious.
Sorry, that's not currently possible. A workaround (depending in what you want to do) might be to export the file as html and show it in a webbrowser (so the user can select the text).
Another option, if by highlighting you mean just painting some cell on a different color, is to paint it in the XlsFile object and refreshing the preview.
Thanks for the very prompt reply, I will have a look at your suggested workarounds.
