The Context Menu is a flyout menu that can be invoked by right-clicking or pressing and holding a UI element. It provides end-users with the ability to perform actions linked to this element.
Context Menus are represented by the ContextMenu class. You can add a context menu to any UI element using the ContextMenu.Menu attached property. The ContextMenu.Content property specifies the flyout content that can be represented by a Windows.UI.Xaml.UIElement descendant or Windows.UI.Xaml.DataTemplate instance.
