Displaying SubReport Data into a Microsoft Report Viewer Control with ASP.NET VB

Question

I've got the main report displaying just fine. Can't get the subreport to display data. Parameters are setup and linked appropriately, but still nothing. Am I missing something obvious? Is there a bug I'm not aware of? Anyone else fighting with this? I'm using Visual Web Developer Express 2008 on a SQL Express 2005 database.

Answer 1

Have you handled the SubreportProcessing event?

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    AddHandler ReportViewer1.LocalReport.SubreportProcessing, AddressOf Me.SubreportProcessingEventHandler
End Sub

Public Sub SubreportProcessingEventHandler(ByVal sender As Object, ByVal e As Microsoft.Reporting.WebForms.SubreportProcessingEventArgs)
    'TODO
End Sub
