The problem is the datasource for the report. Since it is a local rdlc file that was copied from another solution, it no longer has the benefit of the datasource that was originally assigned to it. You must be setting the datasource manually to a datatable or to the result of a linq to sql query. To correct the problem, create a new datatable object, fill it with the results of your report query, and then assign it as the datasource for your report.
