Could you please elaborate a bit more on the issue you are facing? As far as I understand the appointment start time is set to 8:00 and the end time is set to 11 but it appears on the calendar from 8:00 to 8:30. If this is not the problem you are facing please explain what you are trying to achieve and what actually happened.
Please note that the RadScheduler NumberOfHoveredRows
property controls how many time slots to be highlighted when user hovers on the calendar area.
