Examples

This example shows how to bind a SchedulerView instance to a data source that stores custom appointment (MedicalAppointment) and label (MedicalAppointmentType) objects.

  1. Assign a view model object to the content page's BindingContext property.
  2. Set the SchedulerView.DataSource property to a DataSource object and specify the following properties of this object:

    using System;
    using System.Collections.ObjectModel;
    using Xamarin.Forms;
    
    namespace SchedulerExample.Models {
        public class MedicalAppointment {
            public int Id { get; set; }
            public DateTime StartTime { get; set; }
            public DateTime EndTime { get; set; }
            public string Subject { get; set; }
            public int LabelId { get; set; }
            public string Location { get; set; }
        }
    
        public class MedicalAppointmentType {
            public int Id { get; set; }
            public string Caption { get; set; }
            public Color Color { get; set; }
        }
    
        public class ReceptionDeskData {
            public static DateTime BaseDate = DateTime.Today;
    
            public static string[] AppointmentTypes = { "Hospital", "Office", "Phone Consultation", "Home", "Hospice" };
            public static Color[] AppointmentTypeColors = { Color.FromHex("#9c63ff"), Color.FromHex("#64c064"),
                                                        Color.FromHex("#eead51"), Color.FromHex("#d2504b"),
                                                        Color.FromHex("#4b6bbf") };
