There is no shame in it. You make a change to your HtmlViewer.css style sheet, and the changes are not being reflected in Report Manager. It happens to lots of guys. But, help is on the way. Maybe.
This whole situation came about when I made a change to my HtmlViewer stylesheet on my development machine, which worked. When that same change was made to a test server, it didn’t. The style I changed was pretty straight-forward – it just hides the Atom icon in Report Manager:
While poking around, I looked in the rsreportserver.config file, which was located in the “C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer” folder on my machine. I found that in the machine that worked, the “HTMLViewerStyleSheet ” element was there, and the one that didn’t, that same element was missing:
After making this change, the Reporting Services service will need to be restarted.
See your doctor if your style changes don’t last more than four hours.
