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

Declaration

VB.NET

Public Property AllowAppointmentConflicts As AppointmentConflictsMode

Property Value

Type	Description
AppointmentConflictsMode	A AppointmentConflictsMode enumeration value specifying whether the time interval of two or more appointments can intersect or not, if these appointments belong to the same resource(s).

Property Paths

You can access the OptionsCustomization.AllowAppointmentConflicts property from the following objects:

Object Type	Path to AllowAppointmentConflicts
SchedulerControl	.OptionsCustomization.AllowAppointmentConflicts

Remarks

By default, end-users can share the schedule time between two or more appointments. Use the AllowAppointmentConflicts property to control the availability of this functionality to end-users.

If this property is set to AppointmentConflictsMode.Allowed, the time interval of two or more appointments can intersect and sharing the schedule time between the appointments is allowed. Set the AllowAppointmentConflicts property to AppointmentConflictsMode.Forbidden to prevent scheduling (or rescheduling) of two or more appointments for the same time.

NOTE

If the AllowAppointmentConflicts property is set to AppointmentConflictsMode.Custom, then whether an end-user is allowed to share the schedule time between two or more appointments or not is decided in the SchedulerControl.AllowAppointmentConflicts event handler.

Examples

This example demonstrates how to prevent end-users from creating appointments within a certain time interval (from 2 PM to 3 PM). To implement end-user restrictions, handle the SchedulerControl.AllowAppointmentCreate event to prevent end-users from creating appointments within a certain time interval and the SchedulerControl.AllowAppointmentConflicts event to prevent an existing appointment from being dragged to the same time interval:
