I'm working on a SharePoint 2010 solution and I am trying to add a calculated column to an existing list. The column should display rendered html, but displays html encoded html. This problem occur only when adding columns to the existing list. When creating a new list and adding the same calculated column, the html is displayed correctly.
The only visible clue I get is the existing list has blue column headers, while the new list has black column headers. Looks like different aspx/ascx files are handling the output. How do I solve this problem? Can I locate the page responsible for rendering the list?
Thank you for any help!
