我试图以横向或纵向打印本地报告。
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; }
}
我有两个不同的报告,一个是纵向模式,另一个是横向模式,但是我为PageWidth和PageSize更改的值无关紧要,它始终以纵向打印。我已经在11.7英寸和8.3英寸之间交换宽度和高度,但它始终以纵向模式打印。
答案
您可以使用ReportPageSettings.IsLandscape
属性来验证报告是否定义为横向(报告属性>页面设置>方向)。
如果是横向,您需要在DeviceInfo
声明中交换纸张宽度和纸张高度。
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。
Dim printDoc As New PrintDocument
printDoc.DefaultPageSettings.Landscape = rdlLocalReport.GetDefaultPageSettings.IsLandscape
