Suppress Printing

Question

How could I suppress exporting report if no records are loaded using sdk? If setting options in report to suppress i get blank page in pdf when exporting, is there a way to evaluate if fields have data or not? Is there a way to retrieve sql statement sent to database from report evaluate the statement and see if there are rows returned. Help!!!

You can use RAS InProc to find out how many records are in your result set. This works if you are using Crystal Reports XI R1 SP2 (or something newer).
This does not work with: Crystal Reports 9, 10, or any of the bundle editions of Crystal Reports (9.1, 10.2, 10.5).
Here is a sample.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.DataDefModel;
namespace ras115_get_row_count
public partial class Form1 : Form
public Form1()
InitializeComponent();
private void button1_Click(object sender, EventArgs e)
ReportDocument boReportDocument = new ReportDocument();
ISCDReportClientDocument boReportClientDocument = null;
RowsetController boRowsetController;
RowsetCursor boRowsetCursor;
int rows;
boReportDocument.Load(Application.StartupPath + "\\..\\..\\CrystalReport1.rpt");
boReportDocument.Refresh();
boReportDocument.SetParameterValue(0, 12);
boReportClientDocument = boReportDocument.ReportClientDocument;
boRowsetController = boReportClientDocument.RowsetController;
boRowsetCursor = boRowsetController.CreateCursor(new GroupPath(), new RowsetMetaData(), 0);
rows = boRowsetCursor.RecordCount;
MessageBox.Show(rows.ToString());
boReportDocument.Close();
