To solve this problem - SSRS shows wrong form I tried to clear the SSRS cache. One post suggested that I use SQL to do so - http://social.msdn.microsoft.com/Forums/sqlserver/en-US/58caa380-ece8-4507-9ff3-684c93685e72/how-to-clear-a-report-cache-in-ssrs-2008?forum=sqlreportingservices
The code -
Use ReportServer
EXEC FlushReportFromCache @Path
EXEC CleanExpiredCache
@Path you need to give path for report for which you need to clear cache.
Which path do I enter here ? I entered the folder which contains all my rdlc files and the sql gave me 0 rows returned. I am doing simple beginner exercises on a local system.
