I had posted this question on MSDN Forum
But I am not getting any response. Can you please help me. I am really stuck with this rather simple task.
My code seems to be correct but still I get the
A data source instance has not been supplied for the data source 'DataSet1_Order_Details'.
Sorry for the cross post...
I solved the error.
I was adding the data source like
this.ReportViewer.Localreport.DataSource.Add (new RemoteDataSource("DataSet1_Order_Details", ObjectDataSource2.ID));
instead the data source should be added in the following manner
DataSet1TableAdapter.OrderDetails od = new DataSet1TableAdapter.OrderDetails(); ((LocalReport)e.report).Datasources.Add(new RemoteDataSource("DataSet1_Order_Details", od.get(orderid))
this resolved the issue and now I am able to have drill down in the ReortViewer report.
