AppointmentStorage.CustomFieldMappings Property

Provides access to the collection of objects, representing mappings of the appointments' custom properties to appropriate data fields.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v20.1.dll

Declaration

public AppointmentCustomFieldMappingCollection CustomFieldMappings { get; }
Public ReadOnly Property CustomFieldMappings As AppointmentCustomFieldMappingCollection

Property Value

Type Description
AppointmentCustomFieldMappingCollection

An AppointmentCustomFieldMappingCollection object.

Remarks

You can define a custom field via the AppointmentCustomFieldMappingCollection.Add(AppointmentCustomFieldMapping) method; then, create an appointment via the SchedulerStorageBase.CreateAppointment method (so the newly created custom field mappings will be preserved for a new appointment), and pass the custom field value. After you add the appointment to the SchedulerStorage.Appointments collection, you can extract the object contained within the custom field by specifying its name.

IMPORTANT

This API is intended to be used with the legacy SchedulerStorage only. Starting with version 18.1, SchedulerStorage and all of its satellite storages are replaced with their updated versions.

Examples

The code sample below illustrates how to create an appointment with a custom field and use this field in the SchedulerDataStorage.FilterAppointment event to hide appointments which meet certain criteria.

To define a custom field, create a new custom field mapping and add it to the collection of custom mappings using the CustomFieldMappingCollectionBase<T>.Add method. If the Scheduler is not bound to a data source, specify any non-empty string as the data field name.

Create an appointment using the SchedulerDataStorage.CreateAppointment method (so the newly created custom field mappings will be preserved for a new appointment). Set the value for the custom field and add the appointment to the SchedulerDataStorage.Appointments collection.

In the SchedulerDataStorage.FilterAppointment event handler, check the value of the custom field to set e.Cancel to true and hide this appointment.

    scheduler.Storage.Appointments.Clear();
    // Handle the FilterAppointment event to display appointments by some criteria.
    scheduler.Storage.FilterAppointment += Storage_FilterAppointment;
    scheduler.DayView.TopRowTime = TimeSpan.FromHours(DateTime.Now.Hour);

    // Add mapping to create a custom field. 
    // If Scheduler is bound to data, the string "DataFieldOne" should match the field name in the data source.
    // For unbound Scheduler, the data field name is required but not used.
    scheduler.Storage.Appointments.CustomFieldMappings.Add(new
       AppointmentCustomFieldMapping("PropertyOne", "DataFieldOne"));
    Appointment apt1 = scheduler.Storage.CreateAppointment(AppointmentType.Normal,
        DateTime.Now, new TimeSpan(1, 0, 0), "Visible Appointment");
    apt1.CustomFields["PropertyOne"] = "Visible";
    scheduler.Storage.Appointments.Add(apt1);
    Appointment apt2 = scheduler.Storage.CreateAppointment(AppointmentType.Normal,
        DateTime.Now.AddHours(2), new TimeSpan(0, 30, 0), "Hidden Appointment");
    apt2.CustomFields["PropertyOne"] = "Hidden";
    scheduler.Storage.Appointments.Add(apt2);
static void Storage_FilterAppointment(object sender, PersistentObjectCancelEventArgs e) {
    e.Cancel = ((Appointment)e.Object).CustomFields["PropertyOne"].ToString() == "Hidden";
}
