Continuing my intrepid journey in the SQL Server 2008 R2 land, I will discuss the new features of the recently-released CTP3. In this blog, I’ll talk about the first new feature that caught my attention – BIDS support for 2008 and R2 projects.
After hearing the outcry from many developers about project compatibility, in R2 Microsoft has decided to support both SQL Server 2008 and R2 report server projects. Similar to Analysis Services, Reporting Services now lets you target a server version in the project deployment settings. There is even a cool Detect Version link that would detect the SQL Server version based on the TagetServerURL setting.
So, you can have a project that targets either edition. What happens when you use R2-specific features, such as the map control, but set the TargetServerVersion to SQL Server 2008?
The map, Map1, was removed from the report. SQL Server 2008 Reporting Services does not support map report items.
I hope this message got improved before R2 ships because BIDS doesn’t actually remove the map control from the report; you just get a build error.
You should know that as with previous versions, you can deploy older RDLs to the server so you don’t have to upgrade your report definitions to R2. For instance, you can deploy RDL 2005 and the server will render the report via the compatibility interfaces without upgrading it to R2 RDL. Notice also that now we have more deployment settings, such as TargetDatasetFolder and TargetReportFolder but that’s a subject for another blog.
