    Customizing Day Content
    In This Topic

    The C1Calendar control allows users to add custom content to day slot. For this, all you need to do is subscribe the DaySlotLoading event and apply custom content such as images in the background of these day slots. This feature allows users to display weather related information on the calendar.

    The image below shows a C1Calendar after adding custom content to day slots. The calendar displays weather related information through various icons.

    The following code example shows how to add custom content to day slots to the C1Calendar control in C#. The example uses the sample created in the Quick Start.

    1. Replace the content of the ViewController.m file with the code given below.
      Objective-C
      Copy Code 
      using Foundation;
using System;
using UIKit;
using C1.iOS.Calendar;


namespace C1Calendar101
{
    public partial class CustomDayController : UIViewController
    {
        public CustomDayController(IntPtr handle) : base(handle)
        {
        }

        public override void LoadView()
        {
            base.LoadView();
            Calendar.DaySlotLoading += OnDaySlotLoading;
            Calendar.Refresh();
        }

        public override void WillAnimateRotation(UIInterfaceOrientation toInterfaceOrientation, double duration)
        {
            base.WillAnimateRotation(toInterfaceOrientation, duration);
            Calendar.Refresh();
        }

        private void OnDaySlotLoading(object sender, CalendarDaySlotLoadingEventArgs e)
        {
            // add weather image for certain days in the current month
            var today = DateTime.Today;
            if (e.Date.Year == today.Year &&
                e.Date.Month == today.Month &&
                e.Date.Day >= 14 && e.Date.Day <= 23)
            {
                var iv = new UIImageView();
                var tv = new UILabel();
                var slot = new UIStackView(new UIView[] { tv, iv });
                slot.Axis = InterfaceOrientation == UIInterfaceOrientation.Portrait || InterfaceOrientation == UIInterfaceOrientation.PortraitUpsideDown ? UILayoutConstraintAxis.Vertical : UILayoutConstraintAxis.Horizontal;

                tv.Text = e.Date.Day.ToString();

                UIImage image;
                switch (e.Date.Day % 5)
                {
                    default:
                    case 0:
                        image = UIImage.FromFile(@"Images/Cloudy.png");
                        break;
                    case 1:
                        image = UIImage.FromFile(@"Images/PartlyCloudy.png");
                        break;
                    case 2:
                        image = UIImage.FromFile(@"Images/Rain.png");
                        break;
                    case 3:
                        image = UIImage.FromFile(@"Images/Storm.png");
                        break;
                    case 4:
                        image = UIImage.FromFile(@"Images/Sun.png");
                        break;

                }
                image = image.ImageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate);
                iv.UserInteractionEnabled = true;
                iv.TintColor = UIColor.Black;
                iv.ContentMode = UIViewContentMode.ScaleAspectFit;
                iv.Image = image;
                e.DaySlot = slot;
            }
        }
    }
