How you can load Mutipage images, save the annotations and navigate throw them using LEADTOOLS v19?

I am attaching a LEADTOOLS v19 sample C# .Net 4.0 project (using Visual Studio 2010) that does the following:
1. Load a Multipage or Single-page image.
2. If the folder that contains the image contains an Annotations XML file with the same name, it loads it automatically using the AnnCodecs.Load method.
3. If the folder that contains the image doesn't contain an Annotations XML file with the same name, it creates a multipage annotation's XML file that contains different containers (a container for each page in the Multipage source images).
4. You can navigate through the image's pages. When you click "Next", the project automatically saves the current annotations to the Annotation's XML file using the AnnCodecs.Save method. The same thing applies when you click the "Prev" button.
5. If you want to save the current annotations directly to the XML file, you can click the "Save current annotations" button.

Thanks,
