The RadTimePicker is a control that displays a range of times from which the user can select a single time. It essentially inherits RadDateTimePicker and sets the InputMode property to TimePicker.

Adding Telerik Assemblies Using NuGet

To use RadTimePicker when working with NuGet packages, install the Telerik.Windows.Controls.Input.for.Wpf.Xaml package. The package name may vary slightly based on the Telerik dlls set - Xaml or NoXaml

Read more about NuGet installation in the Installing UI for WPF from NuGet Package article.

With the 2025 Q1 release, the Telerik UI for WPF has a new licensing mechanism. You can learn more about it here.

Adding Assembly References Manually

If you are not using NuGet packages, you can add a reference to the following assemblies:

Telerik.Licensing.Runtime
Telerik.Windows.Controls
Telerik.Windows.Controls.Input

You can find more info here.

Setting the SelectedTime

The SelectedTime property holds the selected time. Examples 1 and 2 demonstrate how you can set this property in xaml and code behind. For more information, check out the Selection article of the RadDateTimePicker.

Example 1: Setting the SelectedTime in xaml

XAML

 	<telerik:RadTimePicker x:Name="timePicker" SelectedTime="15:00" />

Example 2: Setting the SelectedTime in code

C#
	timePicker.SelectedTime = new TimeSpan(15,0,0);
VB.NET
	timePicker.SelectedTime = New TimeSpan(15,0,0)

In order to take some action when the SelectedTime is changed, you can handle the SelectionChanged event. You can check out all of the available events in the Events article of the RadDateTimePicker.

StartTime, EndTime and TimeInterval

You can limit the times that can be selected by setting the StartTime and EndTime properties. The TimeInterval property allows user to specify the interval between time slots available for selection. For more information, check out the Clock Items.

Example 2: Setting the StartTime, EndTime and TimeInterval

XAML

	<telerik:RadTimePicker x:Name="timePicker" TimeInterval="0:30:0" StartTime="0:0:0" EndTime="7:0:0" />

Setting the ClockItemsSource

You can also populate the RadTimePicker from code behind by setting its ClockItemsSource property to a collection of TimeSpan objects. Example 3 demonstrates how you can achieve this.

Example 3: Setting the ClockItemsSource

C#
	public DataBinding()
	{
	    this.radTimePicker.ClockItemsSource = this.LoadDataObjects();
	}
	public ObservableCollection<TimeSpan> LoadDataObjects()
	{
	    ObservableCollection<TimeSpan> times = new ObservableCollection<TimeSpan>()
	    { 
	       new TimeSpan(9,0,0),
	       new TimeSpan(10,0,0),
	       new TimeSpan(10,5,0),
	       new TimeSpan(10,22,0),
	    };
	    return times;
	}
VB.NET
	Public Sub New()
		Me.radTimePicker.ClockItemsSource = Me.LoadDataObjects()
	End Sub
	Public Function LoadDataObjects() As ObservableCollection(Of TimeSpan)
		Dim times As New ObservableCollection(Of TimeSpan)() From {
			New TimeSpan(9,0,0),
			New TimeSpan(10,0,0),
			New TimeSpan(10,5,0),
			New TimeSpan(10,22,0)
		}
		Return times
	End Function
