By default, the Movable property is False. If the Movable property on True, the hand cursor is shown when the mouse is hovering the timer object, and the user can click and drag the timer to a new position/time. The Time property indicates the date/time to show the timer. The AllowMoveMarkTime property indicates the keys to allow user to move timers ( with the Movable property on True ). The MarkTimeFromPoint property indicates the timer from the cursor. 

In conclusion, the control supports:

• fixed timers, so the user can not click and drag the timer to a new position/time, if the Movable property is False.
• movable timers, so the user can move the timer by clicking it and drag to a new position/time, if the Movable property is True.

The LayoutStartChanging(exScheduleMoveMarkTime) event notifies once the user is about to move a timer. The MarkTimeFromPoint property indicates the timer from the cursor. The LayoutEndChanging(exScheduleMoveMarkTime) event notifies your application once a MarkTime object is moved, at runtime.

The following snippet of code shows how to get notified once the user moves at runtime the timer. The sample holds the timer from the cursor once the LayoutStartChanging( exScheduleMoveMarkTime) event occurs, and when the LayoutEndChanging( exScheduleMoveMarkTime) event is fired, the previously saved timer, is displayed with the new time.

Dim mtChange As MarkTime

Private Sub Schedule1_LayoutStartChanging(ByVal Operation As EXSCHEDULELibCtl.LayoutChangingEnum)
    If (Operation = exScheduleMoveMarkTime) Then
        Set mtChange = Schedule1.MarkTimeFromPoint(-1, -1)
    End If
End Sub

Private Sub Schedule1_LayoutEndChanging(ByVal Operation As EXSCHEDULELibCtl.LayoutChangingEnum)
    If (Operation = exScheduleMoveMarkTime) Then
        If Not (mtChange Is Nothing) Then
            Debug.Print "Timer has been moved to " & mtChange.Time
        End If
    End If
End Sub
