C# Класс PhotoSharingApp.Universal.Controls.NavMenuListView

A specialized ListView to represent the items in the navigation menu.
This class handles the following: 1. Sizes the panel that hosts the items so they fit in the hosting pane. Otherwise, the keyboard may appear cut off on one side b/c the Pane clips instead of affecting layout. 2. Provides a single selection experience where keyboard focus can move without changing selection. Both the 'Space' and 'Enter' keys will trigger selection. The up/down arrow keys can move keyboard focus without triggering selection. This is different than the default behavior when SelectionMode == Single. The default behavior for a ListView in single selection requires using the Ctrl + arrow key to move keyboard focus without triggering selection. Users won't expect this type of keyboarding model on the nav menu.
