The following properties accept/return SchedulerHitTest values:
Remarks
The SchedulerHitTest enumeration’s values are returned by the SchedulerHitInfo.HitTest property of a SchedulerHitInfo object. Note, that SchedulerHitInfo objects can be created by calling the scheduler’s SchedulerViewInfoBase.CalcHitInfo method.
Example
The following examples demonstrate how to handle the SchedulerControl.MouseMove event and calculate the hit information for the point which the mouse pointer is currently hovering over. The information on the element located under the mouse pointer is shown within the form caption.
The second parameter of the SchedulerViewInfoBase.CalcHitInfo method enables you to specify whether you need information on an appointment being clicked, or on a scheduler element located underneath.
When you drag an appointment over the scheduler, you can use the SchedulerViewInfoBase.CalcHitInfo method to determine the scheduler area below. If you drag appointment to the All-Day Area, you can cancel the action.
