This example demonstrates RadMenuStrip's orientation
support. The Orientation property determines the orientation
of the control and takes two values: Horizontal (default) and Vertical. When
Orientation is set for the menu, its value will determine
the flow of the root group as well.
You can set Orientation property programmatically in the following
way:
this.radMenu1.Orientation = Telerik.WinControls.Layouts.StripOrientation.Vertical;
