Visual Basic

Private Sub ultraMonthViewMulti1_BeforeMonthScroll(ByVal sender As System.Object, ByVal e As Infragistics.Win.UltraWinSchedule.BeforeMonthScrollEventArgs) Handles ultraMonthViewMulti1.BeforeMonthScroll

    '	The BeforeMonthScroll event is a "cancelable" event,
    '	which means that the action to which it corresponds can be
    '	prevented from happening by canceling the event.
    '	
    '	Canceling an event is very simple - just set the 'Cancel'
    '	property of the event arguments to true. The action will then
    '	be prevented from happening, and the corresponding "After"
    '	event will not fire.

    '	If the new first visible month is not in the current year,
    '	cancel the event
    If (e.NewFirstMonth.Year.YearNumber <> DateTime.Today.Year) Then
        e.Cancel = True
    End If

End Sub
