    We have an old legacy Silverlight app we've been asked to try and add functionality.  Our Silverlight is a typical line of business app that has a sql backend and we use WCF services to interface with SQL.  We've been asked to come up with a way to display pdf files.  On our internal server, we have the pdf's stored and we can return them via a stream via WCF.  We can't just redirect users to an html page because of security reason.

    The overview is we have sales orders in a grid, we'll need to create a grid column that contains a ticket number.  The user will click on that if they want to see the ticket in pdf format.  The click will need to initiate a call to a service endpoint what will lookup the pdf file by ticket number and return it as a stream.  We need to then take that stream and display it in a now window.  I was thinking about a taking the stream, and opening up a Rad Window to display the PDF Viewer.  The controls we have from back then don't contain the PDF viewer.

    Is this doable, are there any samples I can use to show this is viable to put in a req for the new control?  Thanks

    Hello Kris,

    All recent versions of Telerik UI for Silverlight contain both RadWindow control and RadPdfViewer control, so the scenario is feasible. You can check the Showing a File help article which list the different way to load a PDF file in RadPdfViewer, but it seems that in the described scenario you could use PdfDocumentSource:

    pdfViewer.DocumentSource = new PdfDocumentSource(stream);

    Working samples with RadPdfViewer could be found in the XAML SDK Repo, for example PdfViewer/First Look, and in the demos application (works only in supported browsers like Internet Explorer).

    Progress Telerik
