Example
The following code demonstrates how to use the UltraDayView's Event Manager to enable/disable events and event groups, and to check to see whether specific events or event groups are enabled.

Imports Infragistics.Win.UltraWinSchedule

	Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click

		' Get the UltraDayView's event manager.
		' The event manager is used to temporarily disable events
		' to prevent them from being raised. This can be very
		' convenient in a situation where one or more properties
		' are being set in code and the events they would normally 
		' raise would cause unnecessary or counter-productive
		' code to be executed.

		' Note: All events are enabled by default.
		Dim eventManager As DayViewEventManager = Me.UltraDayView1.EventManager

		' Select the same time slot in the next day.

		' events to be raised. However, since the above code disabled
		' the events they won't be.

		' all events will a single line of code. If any event is 
		' disabled the 'AllEventsEnabled' property returns false.

		' to see if an event is enabled or disbled.
		If (Not eventManager.IsEnabled(DayViewEventIds.BeforeAppointmentEdited)) Then

			Debug.WriteLine("The BeforeAppointmentEdited event can be fired at this time.")
