public TimelineViewActivityScrollButtonVisibility ActivityScrollButtonVisibility {get; set;}
When the amount of vertical space available in which to display appointments and holidays is less than that required to display all of the visible activity for the currently visible date/time range, up/down facing triangular buttons appear within the ActivityAreaUIElement. These buttons provide a way for the user to scroll non-visible activity into the viewable area.
The size of the buttons defaults to (12 x 12). This can be changed for all UltraTimelineView instances by directly setting the static ElementSize member.
