    Hi Abod, 

    Thank you for writing.

    To prevent adding appointments the same time that there is already another appointment you can cancel the scheduler's 
    AppointmentEditDialogShowing event. Also you can access all appointments and their dates from the scheduler's Appointments collection. You can control where the appointments are moved through the appointment related events like AppointmentMoving and AppointmentDropping.

    For more information please refer to the scheduler
    documentation page.

    I hope this helps.

    RadChart for WinForms is obsolete. Now what?

    The team I've happened to work today already upgraded their stuff to UI for WinForms Q2 2015 and I'm looking for ways to disallow overlapping appointments.

    What would you suggest specifically in regarding to AppointmentMoving and AppointmentDropping you mention above, Peter? Canceling these events as well or something else we can do?

    Is there any updates to this in terms of coding strategy that enables Winform RadSchedule to accept non overlapping appointments only? Looks like there is only work-around for ASP.NET RadScheduler in this aspect? Thx.

    Hello Travis,

    Thank you for writing.

    There is no built-in mechanism for preventing overlapping appointments in RadScheduler. The suggested approach by my colleague, Peter, is applicable for preventing overlapping appointments in the newer versions as well. The AppointmentMoving and AppointmentDropping events are suitable for handling overlapping appointments. In the AppointmentMovingEventArgs, you have information about the NewDate. Thus, you can iterate all appointments in RadScheduler and check if the event dates are in conflict with the one being moved. A similar approach can be followed in the AppointmentDropping event.

    I hope this information helps. Should you have further questions I would be glad to help.
