There are several properties of the Event Calendar Pro add on feature that can be configured from the theme.skin file in the skin folder.
To use these properties you must first add this near the top of the theme.skin file if it does not already exist there:
<%@ Register Namespace="sts.Events.Web.UI.Controls" Assembly="sts.Events.Web.UI" TagPrefix="ecp" %>
Then you can set the available properties which are shown below with their default values:
Valid values for OverrideDefaultView are ListView, WeekView, DayView, TimelineView, or MonthView.
Note that you would add SkinID="ListViewModule" to control settings in the separate List View, whereas no SkinID controls the main List View in the Event Calendar Pro instance.
