Scheduler allows users to add, update, resize, drag, and delete appointments. To control these operations, specify properties in the editing object. In this demo, you can use the checkboxes below the Scheduler to toggle the edit operations.

These operations raise events that you can handle with the following functions:

In this demo, we configured the handlers to display a toast message after a user performs an edit operation.

Users can edit appointment data in the appointment details form. To open it, they need to double-click the appointment. You can use the onAppointmentFormOpening function to customize the form.
