DxScheduler.AppointmentUpdated Event

Fires after an updated appointment is saved to the AppointmentsSource object.

Assembly : DevExpress.Blazor.v25.2.dll

Declaration

csharp

[Parameter]
public EventCallback<DxSchedulerAppointmentItem> AppointmentUpdated { get; set; }

Parameters

Type	Description
DxSchedulerAppointmentItem

A DxSchedulerAppointmentItem object that stores an updated appointment.

Remarks

Use the AppointmentUpdated event to access an updated appointment after it has been saved to the AppointmentsSource object.

Note

To cancel an appointment update or access the updated appointment and change it (if needed), use the AppointmentUpdating event.

The following code snippet does the following:

Creates a DxSchedulerDataStorage object, sets its AppointmentsSource to null.
Assigns the created data storage object to the Scheduler’s DataStorage property.
In the OnInitialized lifecycle method, creates a new DbContext and loads data from the DbContext to the DxSchedulerDataStorage.AppointmentsSource property.
Handles AppointmentInserted, AppointmentUpdated, and AppointmentRemoved events to implement CRUD operations in the Scheduler. To access a target appointment, the SourceObject property is used.
Uses the DbContext.Dispose method to track the context for the component lifetime.
