By default, the navigation orientation of the Calendar control is in horizontal direction. However, you can change the navigation orientation of the calendar to Vertical direction by using Orientation property of the C1Calendar class.

As you can observe from the GIF above, the navigation buttons help the user to navigate the calendar up and down.

The following code demonstrates how to set the vertical navigation orientation using the Orientation property:

<c1:C1Calendar x:Name="calendar" HorizontalAlignment="Left" VerticalAlignment="Top" Orientation="Vertical" >
