            ParameterFieldDefinition crParameterFieldDefinition ;
            ParameterValues crParameterValues = new ParameterValues();
            ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue();
            
            crParameterDiscreteValue.Value = cmbChallanno.Text  ;
            crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields;
            crParameterFieldDefinition = crParameterFieldDefinitions["invno"];
            crParameterValues = crParameterFieldDefinition.CurrentValues;
            
            crParameterValues.Clear();
            crParameterValues.Add(crParameterDiscreteValue);
            crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);

            crParameterDiscreteValue.Value = cmbCustname.Text;
            crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields;
            crParameterFieldDefinition = crParameterFieldDefinitions["custName"];
            crParameterValues = crParameterFieldDefinition.CurrentValues;


            crParameterValues.Add(crParameterDiscreteValue);
            crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);

            //crConnectionInfo.ServerName = "YOUR SERVERNAME";
