Hi Eran,
Sorry for the delay in responding you.
In ScheduleControl “Start time and End time” render before the subject of the appoinment, if “Start time" and "End time” don't coincide with time points. This is the default behaviour of the control. When you have “Start time and End time” which coincide's with time points then that won't be render with the subject.
Please refer the browser samples from the below link which illustrtaes the difference clearly:
http://www2.syncfusion.com/samplebrowser/schedule.web/samples/2.0/scheduler-basicfeatures/addingappointments/cs/AddingAppointments.aspxIn the above sample the appoinment with subject "Testing Project1" alone renders with "Start time and End Time". Since the Time " 9:20 - 12:40" is not coincide with time point it renders with the "Start time and End time" values.
Please refer the screen shot from the below link which illustartes the above:
