Preview a Report in Design Mode (VS 2005)

I am working with SQL Server Reporting Services and Visual Studio .Net 2005 Beta 2. In VS 2003 you could preview a report in design mode by clicking on the preview tab. There is no such tab in 2005 Beta 2. Does anyone know how to preview a report in design mode? Thanks.When you are using the Report Controls in local mode (embedded), there is no preview since your application is responsible for creating the data set to bind into the control. You will need to execute your application to preview.

Designer preview is only present in report server mode.
