• Drag appointments from one C1Schedule control to another.

• Drag appointments onto a C1Calendar control.
  Users can drag appointments onto a C1Calendar control at run time if C1Calendar. AllowDrop is True and the Schedule property is not null. The Start property will be changed according to the date selected in the C1Calendar control and the C1Schedule control navigate to that date.
  
  
  Note: if there are several C1Schedule controls in application, appointment will be moved to the C1Schedule control specified in Schedule property.
