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:
ReportParameter lObjParam = new ReportParameter("Sree", aStrSree);
ReportParameter[] lArrParam = { lObjParam };
ReportViewer3.LocalReport.SetParameters(lArrParam);
ReportViewer3.LocalReport.Refresh();
Second Way
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);
What is that I am doing wrong here…
Any help over here please.
