AutoHideGroup objects allow you to create auto-hidden panels in XAML.
Auto-hidden panels are normally hidden from view, and they appear only when hovering over the panel's label. The labels for auto-hidden panels are displayed within bars at the left, right, top and bottom sides of the DockLayoutManager container. An end-user can enable auto-hide mode for a panel by clicking the auto-hide (pin) button.
The bounds of an expanded auto-hidden panel cannot exceed the bounds of the DockLayoutManager.
