It is human nature to look for products with the lowest prices. In the same way, most people search for the lowest airfares among airlines while booking their tickets.
The Syncfusion WinUI Scheduler, with its comprehensive feature set, allows users to design an airfare calendar to display the lowest fares by customizing the month cells.
In this blog, we will see the steps to design an airfare calendar to display the lowest fares using the WinUI Scheduler control with code examples.
Note: If you are new to our control, then refer to the WinUI Scheduler getting started documentation before proceeding.
To design an airfare calendar, we have to customize the WinUI Scheduler’s month cells using the MonthCellTemplate or MonthCellTemplateSelector properties of the MonthViewSettings. The DataContext of the MonthCellTemplate or MonthCellTemplateSelector properties should be MonthCell. You can use the MonthCell class properties, such as DateText, Appointments, and Data, to bind the airfare details in the month cell data template.
Let’s see the steps to implement it!
First, you need to create a custom data model Airline with the required airline data, such as airline name or ID, date, color, and fare details.
using Syncfusion.UI.Xaml.Core;
/// <summary>
/// Represents the airline data properties.
/// </summary>
public class Airline : NotificationObject
{
private DateTime from;
private Brush color;
private string name;
private double fare;
private string cost;
public string Name
{
get { return name; }
set
{
name = value;
RaisePropertyChanged(nameof(Name));
}
}
public DateTime Date
{
get { return from; }
set
{
from = value;
RaisePropertyChanged(nameof(Date));
}
}
public double Fare
{
get { return fare; }
set
{
fare = value;
RaisePropertyChanged(nameof(Fare));
}
}
public string Cost
{
get { return cost; }
set
{
cost = value;
RaisePropertyChanged(nameof(Cost));
}
}
public Brush Color
{
get { return color; }
set
{
color = value;
RaisePropertyChanged(nameof(Color));
}
}
} Then, create the collection of airline data objects and calculate the lowest airfare for each day by comparing the lowest fares of all the airlines.
/// <summary>
/// The airlines view model.
/// </summary>
public class AirlinesViewModel
{
/// <summary>
/// Gets or sets the lowest airfares.
/// </summary>
public List<Airline> LowestFares { get; set; }
/// <summary>
/// Initializes a new instance of the AirlinesViewModel class.
/// </summary>
public AirlinesViewModel()
{
GetLowestFares();
}
/// <summary>
/// Methods to get the lowest airfares.
/// </summary>
private void GetLowestFares()
{
this.LowestFares = new List<Airline>();
List<Airline> fares = GetAllFares();
var currentDate = DateTime.Now.Date;
for (int startdate = -100; startdate < 100; startdate++)
{
var currentDateFares = fares.Where(x => x.Date == currentDate.AddDays(startdate)).ToList();
//Add only lowest fare for the day.
double minimumFare = Math.Min(currentDateFares[0].Fare, Math.Min(currentDateFares[1].Fare, currentDateFares[2].Fare));
this.LowestFares.Add(currentDateFares.Where(x => x.Fare == minimumFare).FirstOrDefault());
}
}
/// <summary>
/// Method to get all the airways fare.
/// </summary>
/// <returns>returns all airways fares</returns>
private List<Airline> GetAllFares()
{
var random = new Random();
var fares = new List<Airline>();
var airwaysFares = new List<double>()
{
90.50, 95.00, 102.66, 200.09, 180.20, 122.10, 138.83,
134.50, 305.00, 152.66, 267.09, 189.20, 212.10, 238.83,
100.17, 101.72, 332.48 ,100.17, 449.68, 378.44, 273.45,
};
for (int startdate = -100; startdate < 100; startdate++)
{
for (int j = 1; j <= 3; j++)
{
var airline = new Airline();
airline.Name = "Airways " + j.ToString();
//// Adding random fares for airways.
airline.Fare = airwaysFares[random.Next(0, 20)];
airline.Cost = "$" + airline.Fare.ToString();
airline.Color = GetAirlineColor(airline.Name);
airline.Date = DateTime.Now.Date.AddDays(startdate);
fares.Add(airline);
}
}
return fares;
}
/// <summary>
/// Methods to get the airline color.
/// </summary>
/// <param name="airlineName"></param>
/// <returns></returns>
private Brush GetAirlineColor(string airlineName)
{
if (airlineName == "Airways 1")
return new SolidColorBrush(Colors.Red);
else if (airlineName == "Airways 2")
return new SolidColorBrush(Colors.Green);
else
return new SolidColorBrush(Colors.Gray);
}
} Now, map the custom airline data object properties to the Scheduler by configuring the AppointmentMapping property. Then, assign the collection of airline data objects to the ItemsSource property to generate the details of Appointments in the MonthCell, which displays the airfare details of the day.
<Window
...
xmlns:Scheduler="using:Syncfusion.UI.Xaml.Scheduler" >
<Scheduler:SfScheduler x:Name="scheduler"
ItemsSource="{Binding LowestFares}"
ShowBusyIndicator="True"
AppointmentEditFlag="None">
<Scheduler:SfScheduler.AppointmentMapping>
<Scheduler:AppointmentMapping Subject="Name"
Notes="Cost"
StartTime="Date"
AppointmentBackground="Color" />
</Scheduler:SfScheduler.AppointmentMapping>
<Scheduler:SfScheduler.MonthViewSettings>
<Scheduler:MonthViewSettings AppointmentDisplayMode="None"
MonthCellTemplateSelector="{StaticResource monthCellTemplateSelector}"/>
</Scheduler:SfScheduler.MonthViewSettings>
</Scheduler:SfScheduler> Now, create a data template selector class to select different custom month cell data templates based on the airfare and assign it to the MonthCellTemplateSelector property of the MonthViewSettings.
As I said before, you can use the MonthCell data context class properties, such as DateText, Appointments, and Data, to bind the airfare details in the month cell data template.
Refer to the following code example.
public class MonthCellTemplateSelector : DataTemplateSelector
{
public DataTemplate MonthCellWithBestPriceTemplate { get; set; }
public DataTemplate MonthCellWithoutBestPriceTemplate { get; set; }
/// <summary>
/// Template selection method.
/// </summary>
protected override DataTemplate SelectTemplateCore(object item, DependencyObject container)
{
var appointments = item as List<ScheduleAppointment>;
foreach (var app in appointments)
{
var ailrline = app.Data as Airline;
if (ailrline.Fare <= 100.0)
return MonthCellWithBestPriceTemplate;
else
return MonthCellLowestPriceTemplate;
}
return MonthCellLowestPriceTemplate;
}
} Now, set the AppointmentEditFlag property as None in the Scheduler to restrict editor opening, and set the AppointmentDisplayMode property as None to keep appointments from displaying on month cells.
