The schedule header displays the names of the groups currently used for grouping schedule appointments.

The image above represents the header of a schedule day view mode with 2 groupings - the default day grouping and a grouping by a schedule group with 3 items ("Work", "Rest" and "Travel").

The schedule header's appearance can be controlled through the following properties:

• Stroke - specifies the stroke to use for the borders of the header labels.
• LabelPadding - the padding to apply to each label of the schedule header.
• DateFormat - the format of dates. Used in day, week and timeline view. Should be a valid DateTime standard or custom string. By default set to "dd dddd", which produces texts like "04 Monday".
• DateRangeFormat - the format of date ranges. Used in month view. By default set to "{0:dd MMM} - {1:dd MMM}", which produces texts like "01 Jan - 07 Jan".
