RecurrenceRangeControl.Pattern Property

Gets or sets the copy of the pattern appointment.

Namespace: DevExpress.Xpf.Scheduler.UI

Assembly: DevExpress.Xpf.Scheduler.v14.2.dll

Declaration

C#

public Appointment Pattern { get; set; }

VB.NET

Public Property Pattern As Appointment

Property Value

Type	Description
Appointment	An Appointment object specifying a copy of the recurrence pattern.

Remarks

Use the Pattern property to specify the copy of the recurrence pattern required to access additional information for filling the RecurrenceRangeControl editors (for example, to access the recurrence end date to be displayed in the End by editor).

Examples

This example demonstrates how to use the RecurrenceRangeControl control on a custom Edit Appointment form to modify the recurrence range of the pattern appointment. To bind the RecurrenceRangeControl control to the recurrence range settings via the RecurrenceVisualController and AppointmentFormController controllers, use the RecurrenceRangeControl.RecurrenceInfo and RecurrenceRangeControl.Pattern properties.

For an example with step-by-step instructions on how to replace a standard Edit Appointment form with a custom one, refer to the Lesson 3 - Create a Custom Edit Appointment Form with Custom Fields document.
