By default, the AllowMoveEventToOtherGroup property is True. The AllowMoveEventToOtherGroup property has effect only, if the control displays the events by groups ( columns ). The GroupID property of the Event specifies the identifier of the Group that hosts the event. If the control displays groups the GroupID property of the newly created event is automatically updated with the group where the event has been created. When the user moves an event from a group to another, at runtime, the GroupID property may be changed, and the UpdateEvent event occurs. The AllowMoveEventToOtherGroup property on False, prevents moving events from a group to another, at runtime.

The control displays groups if:

• ShowGroupingEvents property is True
• The Groups collection has elements. By default, the Groups collection contains no Group objects. Use the Add method of the Groups collection to add new groups to the control.
• The Groups collection contains visible elements ( Visible on True )
