JanmDakhala_Report jdr = new JanmDakhala_Report();
            ReportDocument cryRpt = new ReportDocument();
            cryRpt.Load("C:\\mahaegram\\MAHAeGRAM\\Reports\\etararja.rpt");

            crParameterDiscreteValue.Value = txtArjaNo.Text;
            crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields;
            crParameterFieldDefinition = crParameterFieldDefinitions["अर्जक्रमांक"];

            jdr.crystalReportViewer1.ReportSource = cryRpt;
            jdr.crystalReportViewer1.Refresh();
            jdr.Show();
