In my last post, I showed how to simple it is to remove commands from the user interface and place them into the AppBar. The commands for editing records and adding new records are both hardcoded to which record gets edited and what data gets added. That is not a very user friendly way to edit/add records.
Windows 8 applications can take advantage of Flyouts for tasks such as getting data into an application, presenting a screen for editing a record, and any other interaction with the user. A Flyout is essentially a mini-form or user control (neither term is technically correct, but you get the point, I believe). Instead of swapping the currently displayed content with another screen for editing records and another screen for adding records, using Flyouts can help keep your users focused on their data and the task at hand.
