How to rotate the PDF Document when its is viewed in PDF Viewer Control?

Platform: WinRT |
Control: SfPdfViewer |
Published Date: May 30, 2017 |
Last Revised Date: February 6, 2020 |
.NET Framework: 4.5.1 |
Product Version: 13.4.0.53

We do not support page rotation in PDF document when it is viewed in PDF Viewer Control. However, as a workaround we can achieve this by setting the rotation value in PageSettings of the PDF document as illustrated in the below code snippet

C#:

//Initialize PdfDocument
PdfDocument pdfDocument = new PdfDocument();
 
//Set Rotate property in page settings
pdfDocument.PageSettings.Margins.All = 0;            
pdfDocument.PageSettings.Rotate = PdfPageRotateAngle.RotateAngle90;
 
//Add the pages as PdfTemplate in PDF document
for (int i = 0; i < loadedDocument.Pages.Count; i++)
{
    PdfPage pdfPage = pdfDocument.Pages.Add();
    PdfTemplate template = loadedDocument.Pages[i].CreateTemplate();
    pdfPage.Graphics.DrawPdfTemplate(template, new PointF(0,                   0),pdfDocument.PageSettings.Size);
}
 
//Save and load the document in viewer
MemoryStream memoryStream = new MemoryStream();
pdfDocument.Save(memoryStream);
memoryStream.Position = 0;
            
PdfLoadedDocument ldocument = new PdfLoadedDocument(memoryStream);
pdfViewer.LoadDocument(ldocument);
