Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v19.2.Core.dll

Declaration

public abstract string Name { get; set; }
Public MustOverride Property Name As String

Property Value

Type Description
String

A String value which represents the property name to be mapped.

Remarks

This property should be overridden in descendants of the MappingBase class.

NOTE

Property name is case sensitive, although data field name (MappingBase.Member) can be case-insensitive dependent on the data source characteristics.

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";
}
