Event Data

The event handler receives an argument of type DayOfWeekHeaderClickedEventArgs containing data related to this event. The following DayOfWeekHeaderClickedEventArgs properties provide information specific to this event.

PropertyDescription
DayOfWeek The DayOfWeek object corresponding to the day that was clicked
Remarks

The UltraMonthViewSingle control has no specific action defined for when the DayOfWeek headers are clicked. The DayOfWeekHeaderClicked event can be used to perform an application-specific action when a DayOfWeek header is clicked.

Note: When the control's WeekendDisplayStyle property is set to Compressed, the DayOfWeekHeaderClicked event does not fire for Sunday.

Example
This example selects all days currently displayed by the control that fall on the day of the week that corresponds to the header that was clicked.
