Printing landscape/portrait in rdlc without preview

Question

I am trying to print a local report in either landscape or portrait.

private void Export(LocalReport report)
{
    Warning[] warnings;
    m_streams = new List<Stream>();

    var deviceInfo = new StringBuilder();
    deviceInfo.AppendLine("<DeviceInfo>");
    deviceInfo.AppendLine("<OutputFormat>EMF</OutputFormat>");
    //"11.7in", "8.3in"
    deviceInfo.AppendLine("<PageWidth>11.7in</PageWidth>");
    deviceInfo.AppendLine("<PageHeight>8.3in</PageHeight>");

    deviceInfo.AppendLine("</DeviceInfo>");

    report.Render("Image", deviceInfo.ToString(), CreateStream, out warnings);            
    foreach (var stream in m_streams) { stream.Position = 0; }
}

I have 2 different reports one in portrait mode and one in landscape mode but it doesn't matter what values I change for PageWidth and PageSize, its always printing in portrait. I've swapped width and height between 11.7in and 8.3in but its always printing in portrait mode.

You can use ReportPageSettings.IsLandscape property to verify if the report is defined as landscape (Report Properties > Page Setup > Orientation).

If landscape you need to swap paper width and paper height in your DeviceInfo declaration.

Dim rdlLocalReport As New LocalReport
Dim strDeviceInfo As String

With rdlLocalReport.GetDefaultPageSettings

    Dim intPaperSizeWidth As Integer = 0
    Dim intPaperSizeHeight As Integer = 0

    If .IsLandscape Then
        intPaperSizeWidth = .PaperSize.Height
        intPaperSizeHeight = .PaperSize.Width
    Else
        intPaperSizeWidth = .PaperSize.Width
        intPaperSizeHeight = .PaperSize.Height
    End If

    strDeviceInfo = "<DeviceInfo>" _
        & "<OutputFormat>EMF</OutputFormat>" _
        & "<PageWidth>" & Strings.Replace(intPaperSizeWidth / 100, ",", ".") & "in</PageWidth>" _
        & "<PageHeight>" & Strings.Replace(intPaperSizeHeight / 100, ",", ".") & "in</PageHeight>" _
        & "<MarginTop>" & Strings.Replace(.Margins.Top / 100, ",", ".") & "in</MarginTop>" _
        & "<MarginLeft>" & Strings.Replace(.Margins.Left / 100, ",", ".") & "in</MarginLeft>" _
        & "<MarginRight>" & Strings.Replace(.Margins.Right / 100, ",", ".") & "in</MarginRight>" _
        & "<MarginBottom>" & Strings.Replace(.Margins.Bottom / 100, ",", ".") & "in</MarginBottom>" _
        & "</DeviceInfo>"

End With

If you use PrintDocument you also need to accordingly change PageSettings.Landscape property.

Dim printDoc As New PrintDocument
printDoc.DefaultPageSettings.Landscape = rdlLocalReport.GetDefaultPageSettings.IsLandscape

You can do this using "GetDefaultPageSettings()" from "Report" (LocalReport/ServerReport) and stealing this code from the reportviewer internals:

private string CreateEMFDeviceInfo(int startPage, int endPage)
{
    string text = "";
    PageSettings pageSettings = PageSettings;
    int hundrethsOfInch = pageSettings.Landscape ? pageSettings.PaperSize.Height : pageSettings.PaperSize.Width;
    int hundrethsOfInch2 = pageSettings.Landscape ? pageSettings.PaperSize.Width : pageSettings.PaperSize.Height;
    text = string.Format(CultureInfo.InvariantCulture, "<MarginTop>{0}</MarginTop><MarginLeft>{1}</MarginLeft><MarginRight>{2}</MarginRight><MarginBottom>{3}</MarginBottom><PageHeight>{4}</PageHeight><PageWidth>{5}</PageWidth>", ToInches(pageSettings.Margins.Top), ToInches(pageSettings.Margins.Left), ToInches(pageSettings.Margins.Right), ToInches(pageSettings.Margins.Bottom), ToInches(hundrethsOfInch2), ToInches(hundrethsOfInch));
    return string.Format(CultureInfo.InvariantCulture, "<DeviceInfo><OutputFormat>emf</OutputFormat><StartPage>{0}</StartPage><EndPage>{1}</EndPage>{2}</DeviceInfo>", startPage, endPage, text);
}

private static string ToInches(int hundrethsOfInch)
{
    return ((double)hundrethsOfInch / 100.0).ToString(CultureInfo.InvariantCulture) + "in";
}

That way you get the page orientation and margins as set in the report definition.

`LocalReport` does not have a `PageSettings` property - where are you getting that from? It has a `GetDefaultPageSettings` method, but the data returned by that method is read only. — ekolis, Oct 30 '19 at 18:23
@ekolis I "stole it from the ReportViewer internals" as I said. Microsoft.Reporting.WinForms.ReportViewer has "PageSettings" as a private property. Your object should have such a property somewhere to work with. — Roger Willcocks, Nov 01 '19 at 06:05
