Using calculated column to write html has been well known since SharePoint 2007. I always like to do this because it does not require complex customization on xslt or even SharePoint designer. Today I check out this blog which has more good examples: http://sharepointwijzer.nl/sharepoint-blog/tech/icc-html-calculated-column-sharepoint-view/#ICCadvanced
I would like to share a simple solution to highlight rows in SharePoint list using calculated field.
Simple. Hope this save the time many out there seeking for quick solution.
