Hiding Empty SubReports in 2012

[Eric]

I previously had code to hide my subreports if they are empty.  This code gets an warning now. 

'Public ReadOnly Property ChildElements As Telerik.Reporting.Processing.ProcessingElement.ElementCollection' is obsolete: 'The Telerik.Reporting.Processing.ProcessingElement.ChildElements property is now obsolete. Use Telerik.Reporting.Processing.ElementTreeHelper.GetChildElements() method instead.'

I have looked into the GetChildElements information, but I cannot convert this code properly to remove the warnings.  What is the new way of doing this?

Private Sub subFilesAttached_ItemDataBound(ByVal sender As Object, ByVal e As EventArgs) _
    Handles subFilesAttached.ItemDataBound
    Dim subReport As SubReport = sender
    Dim report As Processing.Report = subReport.InnerReport
    subReport.Visible = report.ChildElements.Find("detail", True).Length > 0
End Sub

Hi Eric,

Here is the correct code snippet:

Private Sub subFilesAttached_ItemDataBound(sender As Object, e As System.EventArgs)
    Dim subReport As Processing.SubReport = DirectCast(sender, Processing.SubReport)
    Dim report As Processing.Report = DirectCast(subReport.InnerReport, Processing.Report)
    subReport.Visible = Telerik.Reporting.Processing.ElementTreeHelper.FindChildByName(report, "detail", True).Length > 0
End Sub

Kind regards,
