Orientation

Values

The Orientation property is of type System.Windows.Controls.Orientation. Possible values are:

• Orientation.Horizontal: the tollbar/tray is oriented horizontal;
• Orientation.Vertical: the tollbar/tray is oriented vertical;
  

You can change the orientation at run-time.

The orientation of the tray overrides the toolbar's orientation, i.e. the layout will respects only the tray's orientation.

Sometime it is necessary to adjust the horizontal and vertical alignments when you have changed the orientation - all this depends on the container that holds the ToolBar or the tray control.
