PdfDocumentSource allows you to load a PDF in FlexViewer control using two methods, LoadFromFile and LoadFromStream, of C1PdfDocumentSource class. The LoadFromFile method loads PDF from the source file and the LoadFromStream method loads a PDf from source stream.

To load PDF from file

The following code uses the LoadFromFile method to load a PDF from source file.

pds.LoadFromFile("..\..\DefaultDocument.pdf")

pds.LoadFromFile(@"..\..\DefaultDocument.pdf");

To load PDF from stream

The following code uses the LoadFromStream method to load a PDF from source stream.

Dim pds As New C1PdfDocumentSource()
'Load report from stream
Dim asm As Assembly = [GetType]().Assembly
Using stream As Stream = asm.GetManifestResourceStream _
        ("PDFDocumentSource_LoadFromStream_VB.Resources.DefaultDocument.pdf")
  pds.LoadFromStream(stream)
End Using

C1PdfDocumentSource pds = new C1PdfDocumentSource();
//Load report from stream
Assembly asm = GetType().Assembly;
using (Stream stream = asm.GetManifestResourceStream
  (@"PDFDocumentSource_LoadfromStream.Resources.DefaultDocument.pdf"))
    pds.LoadFromStream(stream);
