Hi Judie,
Looks like you are having difficulty binding your dataset with the report. Makes sure you have following code done properly:
//prepare report data source
ReportDataSource rds = new ReportDataSource();
rds.Name = "dsProduct_dtProductList";
rds.Value = dsReport.Tables[0];
rpvAbraKaDabra.LocalReport.DataSources.Add(rds);
Make sure the rds.Name property reflect the exact name of your dataset_datatable.
If you don’t mind, you can always send me your code; I can help you debug it. My email: asif.blog@gmail.com
Regards,
Asif
