In order to use RadTimeline control in your projects you have to add references to Telerik.Windows.Controls.DataVisualization.dll, Telerik.Windows.Controls.dll and Telerik.Windows.Data.dll.

This help topic aims to show you how easy and intuitive is to bind the RadTimeline control.

Before continuing with the code sample here's something important that you need to know about the RadTimeline and the way it presents the data. It has two types of occurences(events) - one-time occurence (happens once in a time, like birthday on a lifetime time line). The other type has a periodical occurrence. It requires a strict Start and End time to be presented.

This article will demonstrate the binding of both. Let's start with our business object - a class with 3 properties - a Start and End date for our sample data and a collection of another class. This collection will represent our data so we'll need a duration property of TimeSpan type and a DateTime property.

public class Product
    public IEnumerable<Item> Data { get; set; }

    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }

public class Item
    public TimeSpan Duration { get; set; }
    public DateTime Date { get; set; }
Public Class Product
    Public Property Data() As IEnumerable(Of Item)

    Public Property StartDate() As Date
    Public Property EndDate() As Date
End Class

Public Class Item
    Public Property Duration() As TimeSpan
    Public Property Date As Date
End Class

Now we'll need to set values to the newly created properties and assign an instance of our class (the so called business object) to the DataContext that will be used to bind the RadTimeline:

public MainPage() //MainWindow in WPF

    var startDate = new DateTime(2010, 1, 1);
    var endDate = new DateTime(2012, 2, 1);

    var items = new List<Item>();
    Random r = new Random();
    for (DateTime i = startDate; i < endDate; i = i.AddMonths(1))
        items.Add(new Item() { Date = i, Duration = TimeSpan.FromDays(r.Next(50, 100))} );

    for (int i = 0; i < 15; i++)
        items.Add(new Item()
            Date = startDate.AddMonths(r.Next(0, 25)).AddDays(15)

    this.DataContext = new Product() { Data = items, StartDate = startDate, EndDate = endDate, };
Public Sub New()

    Dim startDate = New Date(2010, 1, 1)
    Dim endDate = New Date(2012, 2, 1)

    Dim items = New List(Of Item)()
    Dim r As New Random()
    Dim i As Date = startDate
    Do While i < endDate
        items.Add(New Item() With {.Date = i, .Duration = TimeSpan.FromDays(r.Next(50, 100))})
        i = i.AddMonths(1)

    For i As Integer = 0 To 14
        items.Add(New Item() With {.Date = startDate.AddMonths(r.Next(0, 25)).AddDays(15)})
    Next i

    Me.DataContext = New Product() With {.Data = items, .StartDate = startDate, .EndDate = endDate}
End Sub

The following XAML creates a RadTimeline and binds it to our prepared collection of data using the properties mentioned in our Properties topic.

<telerik:RadTimeline Height="250"
                    PeriodStart="{Binding StartDate, Mode=TwoWay}"
                    PeriodEnd="{Binding EndDate, Mode=TwoWay}"
                    ItemsSource="{Binding Data}">
        <telerik:YearInterval />
        <telerik:MonthInterval />
        <telerik:WeekInterval />
        <telerik:DayInterval />
