I'm using RadScheduler with TimelineView, i have ExactTimeRendering and it shows the appointments clear.
Since i have the slots with 12hours, i want to adjust an extra hour, but when i resize it always adjust an extra 12hours. 
 
Would be very helpfull to had a property to allow exactappointment drag, so i can resize 1 extra hour instead of 12. Something similar like in radgrid, when resize columns it shows me how much pixels, in this case i want it to show the time.
