I have 7 parameters (3 multi select of string, 1 DateTime, 3 string values) in my SSRS 2008 report, and I have set all the parameters as null in the default value.
It's working fine in my preview window of Visual Studio 2008. But after deployment to my report server, the "NULL" checkbox for the parameter is not checked, causing the report not to get loaded at initially.
