Using the above as a reference I've had great results printing my report. For some reason though the Print Preview window has everything in it except for the actual series items. Even though there are no series items if I hit the Print button from the print preview window it will print all the series objects just fine.

    Public Shared Sub PrintPreview(ByVal V As Visual)

        Dim Report As New Report

        Dim Section1 As New EmbeddedVisualReportSection(V)
        Report.Sections.Add(Section1)

        Report.PageFooter = New TextBlock() With {.Text = My.Application.Info.Description & My.Application.Info.Version.ToString & " - CONFIDENTIAL INFORMATION - " & DateTime.Now.ToString, .VerticalAlignment = VerticalAlignment.Top}
        Report.ReportSettings.PageOrientation = PageOrientation.Landscape
        Report.ReportSettings.HorizontalPaginationMode = HorizontalPaginationMode.Scale
        Report.PageHeader = New TextBlock() With {.Text = My.Settings.TeamName, .VerticalAlignment = VerticalAlignment.Center, .TextAlignment = TextAlignment.Center, .FontWeight = FontWeights.Bold}

        Dim pp As New PrintPreview
        'Method Signature GeneratePreview(Report, bool showPrintDialog, bool   showReportProgressControl

        pp.xamReportPreview1.GeneratePreview(Report, False, True)

        pp.ShowDialog()
    End Sub

The 3rd line from the bottom is where the series items are actually added. What I mean is that if you look at the chart being passed into this subroutine it will have nothing in its series collection. Once the GeneratePreview method is called then the series items are added. I tried removing a series item from the Series collection and then adding it back to get it to 'redraw' but this made no difference. Any ideas?
