AppointmentImageInfo Class

Provides information on the image object displayed within the appointment.

Namespace: DevExpress.XtraScheduler.Drawing

Assembly: DevExpress.XtraScheduler.v18.1.dll

Declaration

C#

public class AppointmentImageInfo :
    AppointmentImageInfoCore

VB.NET

Public Class AppointmentImageInfo
    Inherits AppointmentImageInfoCore

Remarks

Handle the SchedulerControl.InitAppointmentImages event to customize the images that are displayed within each appointment. An appointment can display either one or more standard or custom images. The collection of these images can be accessed via the AppointmentImagesEventArgs.ImageInfoList property.

Every AppointmentImageInfo object provides information on the image itself, its index, type and visibility state. Use the AppointmentImageInfo.Image, AppointmentImageInfoCore.ImageIndex, AppointmentImageInfoCore.ImageType and AppointmentImageInfoCore.Visible properties correspondingly to customize the image shown within a particular appointment.

Example

The following example handles the SchedulerControl.InitAppointmentImages event to display a custom image within the exception appointment.

The image below shows the result:

C#

using DevExpress.XtraScheduler;
using DevExpress.XtraScheduler.Drawing;
// ...

private void schedulerControl1_InitAppointmentImages(object sender, AppointmentImagesEventArgs e) {
    if(e.Appointment.IsException) {
        AppointmentImageInfo info = new AppointmentImageInfo();
        info.Image = SystemIcons.Warning.ToBitmap();
        e.ImageInfoList.Add(info);
    }
}

VB.NET

Imports DevExpress.XtraScheduler
Imports DevExpress.XtraScheduler.Drawing
' ...

Private Sub SchedulerControl1_InitAppointmentImages(ByVal sender As Object, ByVal e As _
AppointmentImagesEventArgs) Handles SchedulerControl1.InitAppointmentImages
   If e.Appointment.IsException Then
      Dim info As AppointmentImageInfo = New AppointmentImageInfo()
      info.Image = SystemIcons.Warning.ToBitmap()
      e.ImageInfoList.Add(info)
   End If
End Sub
