The report is using the default data that VS sets up for a report based on a data set. This means that the data source for the report is not connecting to the application run-time data, but to the design-time data.
When you select a project DataSet when designing a report, Crystal allows you to design the report based on the class of the DataSet. When you run a report, the data is in an object of the class.
You need to set the DataSource for the report to the instance of the DataSet object that's used by your application. There are a couple of ways of doing this depending on which report object model you're using - CrystalViewer or ReportDocument.
