How to: Create Appointments with Custom Fields

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T224044.

The code sample below illustrates how to create an appointment with a custom field and use this field in the SchedulerStorageBase.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`1.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 SchedulerStorageBase.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 SchedulerStorage.Appointments collection.

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