Gets or sets whether the TileBar is oriented horizontally or vertically.
An Orientation enumeration value that specifies the orientation of the current TileBar. The default is Horizontal.
By default, when the Orientation property is set to Horizontal, tiles in the current TileBar are arranged horizontally, as in the following picture.
Set this property to Vertical to arrange tiles vertically. The result is shown in the figure below.
The TileBar orientation affects the direction in which flyouts open (see TileBar.FlyoutShowDirection).
