Hi Sriram,
Just and FYI... the Designer built into the VS IDE is based on the legacy RDC Embedded report designer, no longer distributable. Because it is legacy and is not 100% functional as the full version of Cr designer previewing reports in the IDE is just for a quick test, it MAY/DOES NOT evaluate the report objects in the same way.
What happens if you run your application and preview in the Form Viewer?You should see the same data as you see in CR 2011.
