Retrieve record count of subreport in Crystal Reports

Question

How can I retrieve the record count of a subreport from within the main report?

Answer 1

1. Put this formula in your subreport. You can suppress it from display if you like.

   whileprintingrecords;
   Shared numbervar SubRecordCount:=(however you want to count the records in the report);

2. Put this in your main report. Again, this can also be suppressed.

   whileprintingrecords;
   shared numbervar SubRecordCount;
   SubRecordCount

3. Use the formula name for #2 for whatever calculations you need.
   IMPORTANT: Due to the fundamental logic of Crystal, you can only use this field if it is BELOW it's subreport.
   Also, as for counting the records in the subreport, I recommend a running total at the bottom of it.

Answer 2

here you can retrive sub report count from code side

===========================

CrystalDecisions.CrystalReports.Engine.ReportDocument RepDoc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();

RepDoc.Load(ReportName);

int IntRepCount = RepDoc.Subreports.Count;

===========================

pass this count to your report

Answer 3

I think this is a dupe, but I'll answer anyway. :)

You can create a formula field on the subreport which contains a shared variable. In the formula you'll set the shared variable to the value of the rowcount field in the subreport.

Then in your main report you will need to create a formula with a shared variable that has the same name as the subreport and then return the value of the shared variable.
