1460787 - How to determine if a Crystal Report has sub-reports when using the CR SDK for VS .NET

Symptom

Resolution

To determine if there are subreports in the main report, we need to loop through all sections of the report as per the code below.

Dim crSections As Sections
Dim crSection As Section
Dim crSubreportObject As SubreportObject
 
'set the crSections object to the current report's sections
crSections = crReportDocument.ReportDefinition.Sections
'loop through all the sections to find all the report objects
For Each crSection In crSections
crReportObjects = crSection.ReportObjects
'loop through all the report objects to find all the subreports
For Each crReportObject In crReportObjects
If crReportObject.Kind = ReportObjectKind.SubreportObject Then
'you will need to typecast the reportobject to a subreport
'object once you find it
crSubreportObject = CType(crReportObject, SubreportObject)
'open the subreport object
crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName)
 
'do what ever from here on
 
Next
End If
Next
