Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v24.1.Core.dll

NuGet Package: DevExpress.Scheduler.Core

Declaration

C#

int Add(
    Appointment appointment
)

VB.NET

Function Add(
    appointment As Appointment
) As Integer

Parameters

Name	Type	Description
appointment	Appointment	An Appointment object to append to the collection.

Returns

Type	Description
Int32	An integer value indicating the position at which the new appointment was inserted.

Remarks

This method adds an Appointment object to the end of the appointment collection maintained by the current AppointmentStorageBase object. This collection can be accessed via the storage’s AppointmentStorageBase.Items property.

To prevent excessive updates when changes to the appointment collection are applied, enclose the code that uses the Add method within calls to PersistentObjectStorage<T>.BeginUpdate and PersistentObjectStorage<T>.EndUpdate methods.

Note

In order to perform the same action at the level of the appointment collection, the collection’s AppointmentCollection.Add method can be used.
