Hi,

Here is some code I am using to display the report. I getting an
error saying "The report has no tables."



  protected void btnExport_Click(object sender, ImageClickEventArgs e)
    {
        CrystalReport cr = new CrystalReport();
        DataTable dt = new DataTable();
        dt.Columns.Add("Column 1", typeof(string));
        dt.Columns.Add("Column 2", typeof(string));

        //generate some random data in the datatable
        Random rnd = new Random();
        for (int i = 0; i < 100; i++)
        {
            dt.Rows.Add(rnd.Next(1, 1000000).ToString(), rnd.Next(1, 1000000).ToString());
        }

        string strReportPath = "CrystalReport.rpt"; // the path of  CrystalReport
        cr.Load(strReportPath);
        cr.SetDataSource(dt);
    }


My question is how can I add a table to the report within the code??

Thanks,

Load fails because the report file "CrystalReport.rpt" has no tables.
you cannot add tables to a report, but you can fill existing tables with data.
for your code to work, you must have a table in the file "CrystalReport.rpt" with exactly the same columns as you defined for dt

one more thing, use ReportDocument instead of CrystalReport
