Calendar and Time view in xamarin form
Calendar and Time view in xamarin form

First we fill add calendar and time template

Download right and left arrow image from google and add in your project.

code is explain in this video.

CalendarTemplate.xaml

 <ContentView xmlns="http://xamarin.com/schemas/2014/forms" 
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
             xmlns:vm="clr-namespace:SchoolUIDesigns.ViewModels"
             x:Class="SchoolUIDesigns.Control.CalendarTemplate">
  <ContentView.Content>
        <Grid RowDefinitions="Auto,Auto" x:DataType="vm:CalendarViewModel">
            <Label Text="{Binding WeekName}" Grid.Row="0"  FontAttributes="Bold" />
            <Label Text="{Binding Date}" Grid.Row="1" HorizontalOptions="Center" FontAttributes="Bold" />
        </Grid>
    </ContentView.Content>
</ContentView>

TimeTemplate.xaml

 <ContentView xmlns="http://xamarin.com/schemas/2014/forms" 
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" 
             xmlns:vm="clr-namespace:SchoolUIDesigns.ViewModels"
             x:Class="SchoolUIDesigns.Control.TimeTemplate">
  <ContentView.Content>
        <Grid RowDefinitions="Auto,Auto" x:DataType="vm:TimeViewModel">
            <Label Text="{Binding Time}" HorizontalOptions="Center" Grid.Row="1" FontAttributes="Bold" />
        </Grid>
    </ContentView.Content>
</ContentView>

Now we will create class

 dd public class CalendarViewModel
    {
        public string WeekName { get; set; }
        public string Date { get; set; }
        public DateTime Dtime { get; set; }
    }

    public class TimeViewModel
    {
        public string Time { get; set; }
    }

    public class CalendarModel
    {
        public List<CalendarViewModel> GetCalendarWeek(DateTime date)
        {
            List<CalendarViewModel> list = new List<CalendarViewModel>();
            try
            {
                DateTime startdate = DateTime.Now.AddDays(3);
                DateTime endate = DateTime.Now.AddDays(30);
                if (date.Date >= startdate.Date && date.Date <= endate.Date)
                {
                    DateTime WeekStartDate = date;
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.ToString("dd"), Dtime = WeekStartDate });
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.AddDays(1).DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.AddDays(1).ToString("dd"), Dtime = WeekStartDate.AddDays(1) });
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.AddDays(2).DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.AddDays(2).ToString("dd"), Dtime = WeekStartDate.AddDays(2) });
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.AddDays(3).DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.AddDays(3).ToString("dd"), Dtime = WeekStartDate.AddDays(3) });
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.AddDays(4).DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.AddDays(4).ToString("dd"), Dtime = WeekStartDate.AddDays(4) });
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.AddDays(5).DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.AddDays(5).ToString("dd"), Dtime = WeekStartDate.AddDays(5) });
                    list.Add(new CalendarViewModel { WeekName = WeekStartDate.AddDays(6).DayOfWeek.ToString().Substring(0, 3), Date = WeekStartDate.AddDays(6).ToString("dd"), Dtime = WeekStartDate.AddDays(6) });
                }
                return list;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
