Assigning Predefined Labels to an Appointment

Assign labels in code or at run time through the Appointment dialog box.

The following code in the Form_Load event assigns the Must Attend label to an appointment:

// Add a new appointment.   
C1.C1Schedule.Appointment app;
app = this.c1Schedule1.DataStorage.AppointmentStorage.Appointments.Add();
// Set some details for the appointment.    
app.Subject = "Meeting";
app.Location = "Large Conference Room";
app.Duration = TimeSpan.FromMinutes(45);
app.Start = new DateTime(2021, 11, 01, 13, 30, 0);
// Assign a predefined label to the appointment.         
app.Label = this.c1Schedule1.DataStorage.LabelStorage.Labels[6];

At run time, open the Label drop-down list in the Appointment dialog box and select one of the available labels.

The following image shows the Must Attend label selected.

Assigning Custom Labels to an Appointment

Assign a custom label by using the Label property. A custom label can specify a color, name, and identifying text.

// Create a new appointment.   
C1.C1Schedule.Appointment app1 = this.c1Schedule1.DataStorage.AppointmentStorage.Appointments.Add();
// Make the appointment an all day event.   
app1.Start = new DateTime(2021, 11, 02, 13, 30, 0);
app1.AllDayEvent = true;
// Set some details for the appointment.   
app1.Subject = "Training";
app1.Location = "Large Conference Room";
// Assign a custom label to the appointment.       
app1.Label = new C1.C1Schedule.Label(Color.DeepSkyBlue, "Meeting", "Meeting");
