Namespace: DevExpress.Web.Mvc

Assembly: DevExpress.Web.Mvc5.v24.2.dll

Declaration

C#

public static T[] GetAppointmentsToUpdate<T>(
    string schedulerName,
    object appointmentDataObject,
    MVCxAppointmentStorage appointmentStorage,
    MVCxResourceStorage resourceStorage
)

VB.NET

Public Shared Function GetAppointmentsToUpdate(Of T)(
    schedulerName As String,
    appointmentDataObject As Object,
    appointmentStorage As MVCxAppointmentStorage,
    resourceStorage As MVCxResourceStorage
) As T()

Parameters

Name	Type	Description
schedulerName	String	The name of a Scheduler as it is specified by the SettingsBase.Name property.
appointmentDataObject	Object	A collection of appointments in the scheduler.
appointmentStorage	MVCxAppointmentStorage	An MVCxAppointmentStorage object that implements the appointment storage functionality and contains mappings.
resourceStorage	MVCxResourceStorage	An MVCxResourceStorage object that implements the resource storage functionality and contains mappings.

Type Parameters

Name
T

Returns

Type	Description
T[]	A Model data class instance that is the entity contained in the appointment data source and mapped to an appointment.

Remarks

The GetAppointmentsToUpdate<T> method creates a fake Scheduler but does not apply all scheduler settings specified in the view, for better performance. Then, an appointment being inserted is retrieved from this Scheduler instance.
