Show master row if no detail rows

markirving

I have a master-detail report and I am putting the master and detail data in the same rows and hiding the master row. This is because my report has only a single (relevant) detail record per master record.

master.field1 master.field2 detail.field1 detail.field2

The problem is that the row does not shoe if there is no detail record for that master record.

I am trying the following:
1. Make a master row that looks like
master.field1 master.field2
2. Only show the master row if there are no detail rows for that master row.

How can I get the number of detail rows for a given master row so I can set the master row visibility in code?

set report to 'Double Pass' and use script :

namespace FastReport
{
  public class ReportScript
  {
    private List<int> list = new List<int>();
    private bool flag;
    
        // MASTER BAND
    private void Data2_BeforePrint(object sender, EventArgs e)
    {
      flag = true;      
      if (Engine.FinalPass)
      {
        int id = (int)Report.GetColumnValue("Orders.OrderID");
        if (list.Contains(id))
          Data2.Visible = false;
        else
          Data2.Visible = true;         
      }             
    }

        // DETAIL BAND
    private void Data1_BeforePrint(object sender, EventArgs e)
    {
      if (Engine.FirstPass && flag)
      {
           int id = (int)Report.GetColumnValue("Order Details.OrderID");
           list.Add(id);
           flag = false;
      }
    }
  }
}

That worked perfectly. Thank-you.
