this code`

  protected void btncreatebill_click(object sender, eventargs e) {     displayreport();  } private datatable totalinfodata() {     try     {         // open sql connection           sqlconnection sqlcon = new sqlconnection(@"data source=pratikpc;initial catalog=dbbilling2.0;integrated security=true");         sqlcon.open();          // create command           sqlcommand sqlcomm = new sqlcommand();         sqlcomm.connection = sqlcon;         sqlcomm.commandtype = commandtype.text;         sqlcomm.commandtext = "select * tbltotalfee class='" + classdropdownlist.selecteditem.value + "'and studentid='" + studentnamedropdownlist.selecteditem.value+"'";          // create instance of northwind datasetxsd           dataset1.tbltotalfeedatatable totalinfodata = new dataset1.tbltotalfeedatatable();          // set data commands           sqldataadapter sqlda = new sqldataadapter(sqlcomm);         sqlda.fill(totalinfodata); // fill data in northwinddataset object.            return totalinfodata;      }      catch (exception ex)     {         throw new exception(ex.message);     } } private void displayreport() {     try     {         // clear data source            reportingforprintingreportviewer.localreport.datasources.clear();          // set datasource report            // first parameter - report dataset name           // second parameter - datasource object i.e datatable           reportingforprintingreportviewer.localreport.datasources.add(new reportdatasource("dataset1", totalinfodata()));          // or set report path           reportingforprintingreportviewer.localreport.reportpath = httpcontext.current.server.mappath("~/report.rdlc");          // refresh , display report           reportingforprintingreportviewer.localreport.refresh();     }     catch (exception ex)     {         throw new exception(ex.message);     } }

why isn't output coming in report?? there rows in database has not been returned. report looks after operation. why aren't rows being displayed?? enter image description here

this datasetenter image description here

try adding schema name before dataset name. like- schemaname_dataset1.

reportingforprintingreportviewer.localreport.datasources.add(new reportdatasource("schemaname_dataset1", totalinfodata()));
