DocumentViewer with Annotations XPS-Store Sample
DocViewerAnnotationsXps shows how to read an XML Paper Specification (XPS) document into a DocumentViewer control and then enable support for adding user-created text note, ink note, and highlight annotations. In this example, user annotations are stored in an XML file as a part within the XPS document.
When executed, the sample displays a menu bar with a "File | Open..." option. When "Open..." is selected, a "File Open..." dialog displays allowing the user to browse and choose an XpsDocument file to open (a sample XPS document file is provided).
When a document is opened, its content is displayed in the DocumentViewer of the main application window. Within the DocumentViewer control you can select a block of text for adding an annotation. Right-clicking on the selected text displays the Annotations context menu allowing you to choose the type of annotation to create: "Highlight", "Text Note", or "Ink Note" annotation. Once the annotation type is selected the annotation highlight or note form displays on the DocumentViewer control. You can add personal comments to text note or ink note annotations. In the DocViewerAnnotationsXps sample, user annotations are stored in an XML file as a PackagePart within the XPS document itself. Using this design, user-annotations are kept together as part of the document package.
The DocViewerAnnotationsXps sample source code consists of five files:
MyApp.xaml - Extensible Application Markup Language (XAML) resources for the application (none in this sample).
MyApp.xaml.cs - Code-behind for creating and displaying the application window.
Window1.xaml.cs - Code-behind supporting the user interface for the main menu and context menu commands.
AnnotationsHelperXps.cs - Annotations helper class to support user annotations stored as part of an XPS document.
A project file and sample XPS document are also provided. To examine the contents of the XPS document and the user annotations XML file contained within, simply change the document file extension from .xps to .zip and then open the file with the Zip utility.
This sample demonstrates a specific feature of the Windows Presentation Foundation and, consequently, does not follow application development best practices.
