This is a small test project to explore an implementation of Drag and Drop in WPF using a TreeView representation of a moderately complex data tree. The sample data comes from a Star Wars fan fiction site.

The data consists of the following:

• Authors that have the following fields:
  • Name - the name of the author
  • Books - the books they have authored. This is really just the list of series that individual stories are associated with.
• Books. As the site doesn't really deal with books, but rather stories, a book for our purposes is simply a set of stories published that are associated together as a series: Books have the following fields:
  • Chapters - this is the list of stories published in the series.
  • Title - this is the name of the series. If there is no real series then the title of the 'book' is the title of the one story the book contains.
• Chapters. As implied above, all chapters must be associated with a book. If a story (chapter) is really a standalone story then it is part of a book with the same name as the story itself. Chapters have the following fields:
  • ChapterName - the title of the story as it was published on the site.
  • Date - the date a story was published on the site

Inside the WpfBooks project the code is organized as follows:

• Author.cs/Book.cs/Chapter.cs - the basic data elements that get moved about.
• Utils.cs - contains the code to generate the sample data.
• MainWindow.xaml.cs - creates the overall UI and has a function to move the observable data from one place to another (moving chapters from one book to another or reorder chapters in a book).
• MainWindowDnd.cs - contains the code for handling all of the Drag and Drop functionality.
