I've been trying to work up a custom tooltip since I don't seem to have any control over what is shown in the default tooltip when hovering over an appointment in an UltraDayView. However,  I can't seem to get the default tooltips turned off. There appears to be a property on the week and month views to supress the default tooltip (TipStyleActivity), but that property doesn't seem to exist for the day view. Is there a way to disable the default tooltip that I've just been missing? Failing that, is there a way to better control what is shown in the default tooltip? Right now, I just end up with my custom tooltip showing up first, and then the default tooltip popping open on top of it a fraction of a second later.

Here is the code I am using to show my custom tooltip. I'm using an UltraToolTipManager :

private void vDays_MouseEnterElement(object sender, UIElementEventArgs e)
        {
            if(e.Element is Infragistics.Win.UltraWinSchedule.DayView.AppointmentUIElement)
            {
                InfWin.Appointment appt = (InfWin.Appointment)e.Element.GetContext(typeof(InfWin.Appointment));
                Infragistics.Win.UltraWinToolTip.UltraToolTipInfo tti =
                    new Infragistics.Win.UltraWinToolTip.UltraToolTipInfo(appt.Subject, ToolTipImage.None, "",
                    DefaultableBoolean.True);
                uwTipMgr.SetUltraToolTip(e.Element.Control, tti);
                uwTipMgr.ShowToolTip(e.Element.Control);
            }
        }

Thanks,
