multiDayView.AllowAppointmentResize = false will not prevent the appointments in MultiDayView from being resized and you should set radScheduler.AllowAppointmentResize instead.

If you drag an appointment to the AllDay area or if you modify its dates, the AllDay property is not updated.

When you select multiple cells in MultiDayView and right-click somewhere to open the context menu, some of the cells will be deselected.

When the Open Item button in the reminder dialog is clicked, the recurring appointment is opened without asking whether you want to open the occurange or the series

1. Create a new project with RadScheduler.
2. Handle the AppointmentMoving event.
3. When handling this event change some property of the Appointment (BackgroundId for example).
4. Run the project.
5. Add some appointments.
6. Try to move an appointment and you will see that the background will remain the same.

Steps to follow:
1. Select cells from 10:00pm (today) to 01:00am (next day).
2. Right click -> New Appointment
3. The Edit Appointment Dialog opens and the End Time is set to 23:59:59 instead of 01:00:00

Allow customizing the Confirm Delete dialog

IMPROVE. RadScheduler - add event that notifies when an appointment is added by the user. The event args should provide information whether the event is added via the edit appointment dialog or via the inline functionality

When RadScheduler is in MultiDayView and you try to change the ruler scale to 5 min using the context menu of the ruler, the application will freeze.

If you create a recurring appointment, delete one of its occurrences and export the calendar, when you import it back the deleted occurrence will be visible.

When ShowAllDayArea is false, and you add an appointment on a single day from 00:00 to 24:00, the appointment will appear twice.

Currently if there are several appointments with equal start date, their order in TimelineView for example cannot be defined via a custom sort comparer.

Currently, when you hit the Delete key, only that occurrence is deleted. There should be a dialog which prompts whether to the delete the whole series or just this occurrence.

When you add simple recurring appointment and edit some of its recurrences to create an exception, then open the series and remove the recurrence by clicking the Remove Recurrence button, the normal occurrences will disappear but the exceptions will still be present.

With the current WeeklyPrintStyle, when you select a StartDate it "jumps" to the previous Monday. There should be a way (another style or improvement to the current weekly style) to select a different week start day.

The first time you drag an appointment after RadScheduler has loaded in grouped DayView mode, if you drag that appointment fast, an exception will be thrown.

The event is not fired in case you select the previously selected appointment in a different resource.

The NewResourceId property of the event arguments on the AppointmentMoved/Moving events is always null. Also the events do not fire correctly the first time when an appointment is moved from one resource to another.

Currently, it is not possible to set for example 9:30 as a start scale for the ruler in DayView and WeekView.

When you use the following code:

this.radScheduler1.GetTimelineView().GetScaling().DisplayedCellsCount = 12;
this.radScheduler2.GetTimelineView().GetScaling().DisplayedCellsCount = 30;  

both schedulers have cells count equal to 30.
