How to access the subreport information using the ReportDocument Object Model.

Visual Studio 2008

Crystal Reports 2008 Service pack 0 or above

To get the subreport information the application has to access the subreport object traversing the main report sections.

Once the subreport object is accessed, the related information can be accessed by using the object properties.

Following sample code displays the name of the subreport using the 'name' property of the subreport object.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 

Dim myReportDocument As New ReportDocument 
myReportDocument.Load(Server.MapPath("report1.rpt")) 
Dim mySections As Sections = myReportDocument.ReportDefinition.Sections 
For Each mySection As Section In mySections 
Dim myReportObjects As ReportObjects = mySection.ReportObjects 
For Each myReportObject As ReportObject In myReportObjects 
If myReportObject.Kind = ReportObjectKind.SubreportObject Then 
Dim mySubreportObject As SubreportObject = CType(myReportObject, SubreportObject) 
Dim subReportDocument As ReportDocument = mySubreportObject.OpenSubreport(mySubreportObject.SubreportName) 
Dim str As String = subReportDocument.Name 
textbox1.text = str 
CrystalReportViewer1.ReportSource = myReportDocument 
End If 
Next 
Next 
End Sub
