Hello, You can try as below public void ItemsSubreportProcessingEventHandler(object sender, SubreportProcessingEventArgs e) { switch (e.ReportPath) { case "CarrierDistributionReport": objCust._CustomerID = Convert.ToInt32(hfCustomerId1.Value); DataSet ds1 = new DataSet(); ds1 = objCust.AuditReport(); ReportDataSource dataSource = new ReportDataSource();dataSource.Name = "DataSet12_AuditReport"; dataSource.Value = ds1.Tables[0]; e.DataSources.Add(new ReportDataSource("DataSet12_AuditReport", ds1.Tables[0])); break; case "CostPerUserReport": objCust._CustomerID = Convert.ToInt32(hfCustomerId1.Value);ds1 = new DataSet(); ds1 = objCust.Get_CostPerUser(); dataSource = new ReportDataSource(); dataSource.Name = "DataSet11_Get_CostPerUser"; dataSource.Value = ds1.Tables[0]; e.DataSources.Add(new ReportDataSource("DataSet11_Get_CostPerUser", ds1.Tables[0])); break; case "PlanAndMinuteReport": objCust._CustomerID = Convert.ToInt32(hfCustomerId1.Value); ds1 = new DataSet(); ds1 = objCust.Get_CostPerUser(); dataSource = new ReportDataSource();dataSource.Name = "DataSet12_AuditReport"; dataSource.Value = ds1.Tables[0]; e.DataSources.Add(new ReportDataSource("DataSet12_AuditReport", ds1.Tables[0])); break; default: break; } } Thanks
