  public MainWindow()
  {
  InitializeComponent();
 
  }
  void LoadFlowDocumentReaderWithXAMLFile()
 
  {
  FlowDocument content = null;
  // Open the file that contains the FlowDocument...
  FileStream xamlFile = new FileStream("Page1.xaml", FileMode.Open, FileAccess.Read);
  // and parse the file with the XamlReader.Load method.
  content = XamlReader.Load(xamlFile) as FlowDocument;
  // Finally, set the Document property to the FlowDocument object that was
  // parsed from the input file.
  FlowDocRdr.Document = content;
 
}
 

  }
