Hello,
I am currently implementing the RadScheduler control where I have already replaced the AppointmentEditDialog and the EditRecurrenceDialog.
Could you point me in the right direction how to replace the message-dialog when you move/resize a single item of a recurrence appointment?
(See attached image)
Best regards

Hello, Patrick,
The AppointmentDraggingBehavior shows the message box illustrated in the attached screenshot. If you need to customize it, it is necessary to create a derivative of the AppointmentDraggingBehavior and override its ValidateOccurrenceDropTarget method. You can find below the default implementation of the method and how to replace the default drag drop behavior:
The RadMessageBox shown at the bottom of the method is the one you need. Feel free to replace it with any dialog that you have constructed.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
