The SaveDocument method expects the input stream will not be closed or modified while a PDF document is saved (the PdfViewer.DetachStreamAfterLoadComplete or PdfViewerControl.DetachStreamOnLoadComplete property is set to false by default). Be aware that disposing of an output stream that has not been detached may cause errors on an attempt to apply further changes to a document. If you want to close the stream when a document is saved, set the PdfViewer.DetachStreamAfterLoadComplete (PdfViewerControl.DetachStreamOnLoadComplete) property to true.
