Pass Values to TextObjects in a Subreport?

I have a report with a subreport in it and that subreport needs to contain information that isn't pulled from the stored procedure that it is linked with to obtain other data. My report runs the subreport many times for each record.

I am needing to pass values to text objects in these individual subreports that is information that is obtained in the code. My code works fine when this subreport is ran on it's own but I can't get the values sent to the subreports. Here is a simple example of some of my code:

 

using (PrintBills reportPrintBills = new PrintBills())
{
    using (CrystalReportBill reportBill = new CrystalReportBill())
    {
        CrystalDecisions.CrystalReports.Engine.TextObject lblBalanceDue = ((CrystalDecisions.CrystalReports.Engine.TextObject)reportBill.Summary.ReportObjects["lblBalanceDue"]);
        CrystalDecisions.CrystalReports.Engine.TextObject lblName = ((CrystalDecisions.CrystalReports.Engine.TextObject)reportBill.Summary.ReportObjects["lblName"]);
 
        DataSet ds = new DataSet();
        GetBills(ref ds, "Bills", date);
        DataView dvID = new DataView(ds.Tables["Bills"]);
        num = 0;
 
        foreach (DataRowView rowID in dvID)
        {
            GetBioInfo(ref ds, "BioData", id);
            DataRow row = ds.Tables["BioData"].Rows[num];
            lblName.Text = row["Stu_Name"].ToString();
            lblBalanceDue.Text = String.Format("{0:C}", row["Amount_Due"]);
            num++;
        }
 
    }
    
    reportPrintBills.SetParameterValue("@tblMonth", date);
    reportPrintBills.SetParameterValue("@begdate", strBegdate);
    reportPrintBills.SetParameterValue("@enddate", strEnddate);
 
    //Export to PDF code here
}

Select allOpen in new window

reportBill does not display the values obviously. Somehow I need to set that reportBill is a subreport of reportPrintBills in the code so that each record will recognize the TextObject values that I am sending to them. I need the values to be different for each subreport.

I have tried the following but this didn't work:

 

using (PrintBills reportPrintBills = new PrintBills())
{
    ReportDocument reportBill = new ReportDocument();
    reportBill = reportPrintBills.OpenSubreport("subReportBill");
    using (reportBill)
    {
        CrystalDecisions.CrystalReports.Engine.TextObject lblName = ((CrystalDecisions.CrystalReports.Engine.TextObject)reportBill.Summary.ReportObjects["lblName"]);

Select allOpen in new window

I get the errors for each of the TextObjects I'm trying to define:

'CrystalDecisions.CrystalReports.Engine.ReportDocument' does not contain a definition for 'Summary'

Am I on the right track here?


Another solution I've tried is adding parameter fields to reportBill and reportPrintBills and linking them up and then passing values like so:

foreach (DataRowView rowCWID in dvCWID)
{
    GetBioInfo(ref ds, "BioData", id);
    DataRow row = ds.Tables["BioData"].Rows[num];
    name = row["Stu_Name"].ToString();
    amtDue = String.Format("{0:C}", row["Amount_Due"]);
    reportPrintBills.SetParameterValue("@strName", name);
    reportPrintBills.SetParameterValue("@strAmtDue", amtDue);
    num++;
}

Select allOpen in new window

But the value stays the same in all of the subreports rather than changing with each pass through due to the fact that it only ends up setting the value of the parameter to the last name that was passed before exporting the pdf.
