Hi,
I am trying to generate report during runtime using some parameters.But I am getting this error
“a data source instance has not been supplied for the data source dataset1”
I have done the following.
1. Created Dataset with query like SELECT * FROM Sreenath where Sree=@Sree. This Sreenath table has got Sree and ID as columns.
2. Tagged it to Report1.rdlc.
3. Attached Report1.rdlc to a reportviewer.
4. While runtime I trying to refresh the report in following ways...
First way:

C#

ReportParameter lObjParam = new ReportParameter("Sree", aStrSree);
ReportParameter[] lArrParam = { lObjParam };
ReportViewer3.LocalReport.SetParameters(lArrParam);
ReportViewer3.LocalReport.Refresh();

Second Way

C#

string lStrReportPath = ReportViewer3.LocalReport.ReportPath;
DataSet2.SreenathDataTable lDS = new DataSet2.SreenathDataTable();
DataSet2TableAdapters.SreenathTableAdapter lAdapter = new DataSet2TableAdapters.SreenathTableAdapter();
lDS = lAdapter.GetDataIds(aStrSree);
int lIntResult = lAdapter.Fill(lDS, aStrSree);
ReportDataSource lDTSource = new ReportDataSource("DataSet2_Sreenath", (DataTable)lDS);
ReportViewer3.LocalReport.DataSources.Clear();
ReportViewer3.LocalReport.ReportPath = lStrReportPath;
ReportViewer3.LocalReport.DataSources.Add(lDTSource);
ReportViewer3.LocalReport.Refresh();

What is that I am doing wrong here…
Any help over here please.

now you try this:-

sqlconnection con=new sqlconnection(//your connection string);
sqlcommand cmd=new sqlcommand("SELECT * FROM Sreenath where Sree=@Sree",con);
cmd.Parameters.AddWithValue("@Sree",//your value);
sqldataadapter adapter=new sqldataadapter();
adapter.selectcommand=cmd;
Dataset ds=new dataset();
adapter.fill(ds);
Microsoft.Reporting.WinForms.ReportDataSource reportDataSource1 = new Microsoft.Reporting.WinForms.ReportDataSource("*.rdlc file datasource", ds.Tables[0]);/*for check datasource name open *.rdlc file and go to report menu->Datasources...*/

reportViewer1.LocalReport.DataSources.Clear();/*Clear datasource*/
            reportViewer1.LocalReport.DataSources.Add(reportDataSource1);/*Add Data Source*/
            reportViewer1.RefreshReport();
