The image combo box control used to select the appointment status in appointment editing dialogs.

Namespace: DevExpress.XtraScheduler.UI

Assembly: DevExpress.XtraScheduler.v24.2.dll

Declaration

C#
VB.NET

[ComVisible(false)]
public class AppointmentStatusEdit :
    ImageComboBoxEdit

<ComVisible(False)>
Public Class AppointmentStatusEdit
    Inherits ImageComboBoxEdit

Remarks

The AppointmentStatusEdit represents a combo box editor with images displayed along with text captions. To link it to a SchedulerStorage you should set its Storage property to that component. When dropped onto a form that contains a Scheduler control, it links itself to a scheduler storage automatically.

The combo box loads information about AppointmentStatus objects and displays the properties of each object as follows:

AppointmentStatus.Type as a text caption,
AppointmentStatus.Brush as the color fill of a rectangular region.

The control tracks the AppointmentStatusCollection changes. You may update information manually by calling the AppointmentStatusEdit.RefreshData method.

The common appearance of the AppointmentStatusEdit is shown in the picture below.

Example

The following example demonstrates how to create a custom form to change the appointment’s label, status and resource. It is intended to illustrate XtraScheduler controls used for editing a non-recurring appointment. For information on how to substitute the standard form with a custom one, please refer to the Getting Started tutorial.

The example below declares a form constructor with parameters - a scheduler control and a current appointment. For this example to work correctly, the form should contain the following auxiliary controls:

edtLabel (of the AppointmentLabelEdit class);
edtResources (of the AppointmentResourceEdit);
edtStatus (of theAppointmentStatusEdit);

You should also add the btnOk button, which is used to confirm the chosen settings and to close the form.
