BeforeActiveOwnerChanged Event (UltraDayView)

Event fired before the active owner has been changed.
Syntax
public event BeforeActiveOwnerChangedEventHandler BeforeActiveOwnerChanged
Event Data

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

PropertyDescription
Cancel (Inherited from System.ComponentModel.CancelEventArgs) 
ClearSelectedActivities Gets/sets whether the SelectedAppointments, SelectedHolidays and (for UltraMonthViewSingleBase derived controls only) SelectedNotes collections should be cleared.
NewActiveOwner Returns the new active owner.
Remarks

This event is fired before the ActiveOwner has changed.

The operation can be canceled from within this event by setting the event args Cancel parameter to true.

Example
The following code sample demonstrates how to use the BeforeActiveOwnerChanged event to prevent a particular owner from becoming activated, and how to use the AfterActiveOwnerChanged event to synchronize the active owner across different controls.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
