Hello, Dominic,
You can create a derivative of EditAppointmentDialog and override its ValidateInput method. It is triggered when the OK button is clicked. Hence, you can perform any additional code in the method.
Additional information about creating custom dialogs in RadScheduler is available in the following help articles:
https://docs.telerik.com/devtools/winforms/controls/scheduler/appointments-and-dialogs/adding-a-custom-field-to-the-editappointment-dialog
https://docs.telerik.com/devtools/winforms/controls/scheduler/dialogs/editappointmentdialog
I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hi Dess, how do I exit the dialog box without saving if the condition is not met?
Please check my pic attachment part highlighted in RED. Thanks.
I tried "Exit Sub" but it still creates the appointment.

Dominic, the ApplySettingsToEvent method is called when the OK button is clicked. If you skip the base logic and just return in the if statement, the changes made on the dialog wouldn't be applied to the affected Appointment.
