Convert WPF (XAML) Control to XPS Document


Can I take an Existing WPF (XAML) Control, databind it and turn it into an XPS document that can be displayed and printed using the WPF XPS Document Viewer? If so, how? If not, how should I be doing ‘reporting’ in WPF using XPS/PDF/etc?

Basically I want to take an existing WPF control, databind it to get useful data into it and then make it printable and saveable for the end user. Ideally the document creation would be done in memory and wouldn’t hit the disk unless the user specifically saved the document. Is this feasible?

Actually after messing around with heaps of different samples, all of which are incredibly convoluted and require the use of Document Writers, Containers, Print Queues and Print Tickets, I found Eric Sinks article about Printing in WPF
The simplified code is a mere 10 lines long

public void CreateMyWPFControlReport(MyWPFControlDataSource usefulData)
  //Set up the WPF Control to be printed
  MyWPFControl controlToPrint;
  controlToPrint = new MyWPFControl();
  controlToPrint.DataContext = usefulData;

  FixedDocument fixedDoc = new FixedDocument();
  PageContent pageContent = new PageContent();
  FixedPage fixedPage = new FixedPage();

  //Create first page of document
  //Create any other required pages here

  //View the document
  documentViewer1.Document = fixedDoc;

My sample is fairly simplistic, it doesn't include Page Sizing and Orientation which contains a whole different set of issues that don't work as you would expect. Nor does it contain any save functionality as MS seem to have forgotten to include a Save button with the Document Viewer.

Save Functionality is relatively simple (and is also from Eric Sinks article)

public void SaveCurrentDocument()
 // Configure save file dialog box
 Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
 dlg.FileName = "MyReport"; // Default file name
 dlg.DefaultExt = ".xps"; // Default file extension
 dlg.Filter = "XPS Documents (.xps)|*.xps"; // Filter files by extension

 // Show save file dialog box
 Nullable<bool> result = dlg.ShowDialog();

 // Process save file dialog box results
 if (result == true)
   // Save document
   string filename = dlg.FileName;

  FixedDocument doc = (FixedDocument)documentViewer1.Document;
  XpsDocument xpsd = new XpsDocument(filename, FileAccess.ReadWrite);
  System.Windows.Xps.XpsDocumentWriter xw = XpsDocument.CreateXpsDocumentWriter(xpsd);

So the answer is Yes, you can take an Existing WPF (XAML) Control, databind it and turn it into an XPS document - and its not all that difficult.
