• Update can pass a null appointment to PopulateAppointment and it also does not return an IActionResult. Add a not-found guard and return the updated object (consistent with other ASP.NET Core samples).

        public IActionResult Update(int key, string values) {
            var appointment = SchedulerData.Appointments.FirstOrDefault(e => e.ID == key);
            // ...
            PopulateAppointment(appointment, values);
        }

• Delete does not return an IActionResult, and it can attempt to remove a null appointment if the key is not found. Add a not-found guard and return a result.

        public IActionResult Delete(int key) {
            var appointment = SchedulerData.Appointments.FirstOrDefault(e => e.ID == key);
            // ...
            SchedulerData.Appointments.Remove(appointment);
        }

• Delete can throw when the specified key is not found (Remove(null) will throw). Add a null check and return NotFound() when no appointment matches the key.

        public IActionResult Delete(int key) {
            var appointment = SchedulerData.Appointments.FirstOrDefault(e => e.ID == key);
            // ...
            SchedulerData.Appointments.Remove(appointment);
            return NoContent();

• The SchedulerDataController snippet is missing the standard using directives and a namespace declaration. As written, it will not compile when copied into an ASP.NET Core project because types like Controller, DataSourceLoadOptions, DataSourceLoader, JsonDocument, and LINQ extensions are not in scope. Add the same header structure used in other ASP.NET Core snippets (for example, concepts/05 UI Components/DataGrid/00 Getting Started with DataGrid/05 Bind the DataGrid to Data.md).

    public class SchedulerDataController : Controller {
        [HttpGet]
        public object Get(DataSourceLoadOptions loadOptions) {
            return DataSourceLoader.Load(SchedulerData.Appointments, loadOptions);
        }

• Update can pass a null appointment into PopulateAppointment(...) when the requested key is not found, which results in a NullReferenceException. Guard against missing records and return a non-success status code (for example, NotFound()) before calling PopulateAppointment.

        [HttpPut]
        public IActionResult Update(int key, string values) {
            var appointment = SchedulerData.Appointments.FirstOrDefault(e => e.ID == key);
            // ...
            PopulateAppointment(appointment, values);
            return Ok(appointment);
        }

• This section refers to DevExtreme "events" (options like onAppointmentAdding), not "event handlers" being called by Scheduler. Also, the onAppointmentDeleting link is inconsistent with the other two and should point to the API reference Markdown page.

When users add, edit, or delete appointments, Scheduler calls the following event handlers:

- [onAppointmentAdding](/api-reference/10%20UI%20Components/dxScheduler/1%20Configuration/onAppointmentAdding.md '/Documentation/ApiReference/UI_Components/dxScheduler/Configuration/#onAppointmentAdding/')
- [onAppointmentUpdating](/api-reference/10%20UI%20Components/dxScheduler/1%20Configuration/onAppointmentUpdating.md '/Documentation/ApiReference/UI_Components/dxScheduler/Configuration/#onAppointmentUpdating/')
- [onAppointmentDeleting](/Documentation/ApiReference/UI_Components/dxScheduler/Configuration/#onAppointmentDeleting)

• After switching to "events" above, this sentence should also refer to events (not handlers) and include the article before Scheduler.

You can use these handlers to extend Scheduler's functionality. The following example configures **onAppointmentAdding** and **onAppointmentUpdating** to prevent adding or moving appointments to cells with existing recurring appointments:
