By default, the EnsureVisibleFaces property is "0,2,1,3,4,5". The EnsureVisibleFaces property specifies the faces that can be fully visible. The EnsureVisibleFace method ensures that specified face is fully displayed on the control. The AlwaysEnsureVisibleFace property indicates whether the control allows fully visible face when the user drags the cube to a different position. Use the AllowEnsureVisibleFaceOnKey property to disable navigating through the faces when user presses SPACE or arrow keys. The VisibleFace property specifies the visible face. The EnsureVisibleFaceMargin property specifies the size of the margin ( left / right ) of the cube's client area to ensure that a face fits it. The EnsureVisibleFaceOnDblClick property ensures that the face being double clicked fits the cube's client area. 

The control may fire the following events, when the user drags the cube to a new position, or if the EnsureVisibleFace /  VisibleFace method is called:

• LayoutStartChanging event notifies that the user starts dragging the cube.
• Rotate / Zoom occurs when any of the following properties RotX, RotY, Zoom are updated
• Move event occurs once a new face became visible, by moving/rotating from a face to another, into the giving direction.
• LayoutEndChanging event notifies that the user ends dragging the cube.
