在没有预览的情况下在 rdlc 中打印横向/纵向 [英] Printing landscape/portrait in rdlc without preview

问题描述

我正在尝试以横向或纵向打印本地报告.

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; }
}

我有 2 个不同的报告，一个是纵向模式，一个是横向模式，但是我更改 PageWidth 和 PageSize 的值并不重要，它总是以纵向打印.我在 11.7 英寸和 8.3 英寸之间交换了宽度和高度，但它始终以纵向模式打印.

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.

推荐答案

您可以使用 ReportPageSettings.IsLandscape 属性以验证报告是否定义为横向(报告属性 > 页面设置 > 方向).

如果横向，您需要在 DeviceInfo 声明中交换纸张宽度和纸张高度.

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

如果您使用 PrintDocument，您还需要相应地更改 PageSettings.Landscape 属性.

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

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