Thank you for writing.
I have attached a sample project demonstrating how to add a third RadRadioButton
in the DeleteRecurringAppointmentDialog
. However, the default OK/Cancel buttons sets the DialogResult
to OK/Cancel respectively. Hence, in order to manipulate the default behavior considering the new radio button, it is suitable to hide the default buttons and add your own and execute the desired logic.
I hope this information helps. Should you have further questions I would be glad to help.
