Getting Started

This article will guide you through the steps needed to add a basic RadSegmentedControl control in your application.

1. Setting up the app

Take a look at these articles and follow the instructions to setup your app:

2. Adding the required Telerik references

You have two options:

  • Add the Telerik UI for Xamarin Nuget packages following the instructions in Telerik NuGet package server topic.

  • Add the references to Telerik assemblies manually, check the list below with the required assemblies for RadSegmentedControl component:

Platform Assemblies
Portable Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Input.dll
Android Telerik.Xamarin.Android.Common.dll
Telerik.Xamarin.Android.Input.dll
Telerik.Xamarin.Android.Primitives.dll
Telerik.Xamarin.Android.List.dll
Telerik.Xamarin.Android.Data.dll
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Input.dll
iOS Telerik.Xamarin.iOS.dll
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Input.dll
UWP Telerik.Core.dll
Telerik.Data.dll
Telerik.UI.Xaml.Input.UWP.dll
Telerik.UI.Xaml.Controls.Data.UWP.dll
Telerik.UI.Xaml.Primitives.UWP.dll
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Input.dll

3. Adding RadSegmentedControl control

If your app is setup, you are ready to add a RadSegmentedControl control.

RadSegmentedControl allows you to work with two types of data - string and image. You can use the ItemsSource property of RadSegmentedControl to provide IEnumerable collection of strings or image sources. The control will display a segment for each item in the items source.

Populate with string data

Here is an example how to set the control's ItemsSource property and populate it with some data.

<telerikInput:RadSegmentedControl x:Name="segmentControlText"
                              HeightRequest="60"
                              VerticalOptions="Start">
    <telerikInput:RadSegmentedControl.ItemsSource>
        <x:Array Type="{x:Type x:String}">
            <x:String>Popular</x:String>
            <x:String>Library</x:String>
            <x:String>Playlists</x:String>
            <x:String>Friends</x:String>
        </x:Array>
    </telerikInput:RadSegmentedControl.ItemsSource>
</telerikInput:RadSegmentedControl>
RadSegmentedControl segmentControlText = new RadSegmentedControl()
{
    VerticalOptions = LayoutOptions.Start, HeightRequest = 60,
    ItemsSource = new List<string>() { "Popular", "Library", "Playlists", "Friends" },
};

You also have to add the following namespace:

xmlns:telerikInput="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.XamarinForms.Input"
using Telerik.XamarinForms.Input;

Populate with image sources

<telerikInput:RadSegmentedControl x:Name="segmentControlImages"
                              HeightRequest="60"
                              VerticalOptions="Start" Grid.Row="1">
    <telerikInput:RadSegmentedControl.ItemsSource>
        <x:Array Type="{x:Type FileImageSource}">
            <FileImageSource>available.png</FileImageSource>
            <FileImageSource>away.png</FileImageSource>
            <FileImageSource>busy.png</FileImageSource>                    
        </x:Array>
    </telerikInput:RadSegmentedControl.ItemsSource>
</telerikInput:RadSegmentedControl>
RadSegmentedControl segmentControlImages = new RadSegmentedControl()
{
    VerticalOptions = LayoutOptions.Start,
    HeightRequest = 60,
    ItemsSource = new List<FileImageSource>() { "available.png", "away.png", "busy.png" },
};

This is the result:

4. Setting segment colors

You can set the background of the segments via the SegmentBackgroundColor property. The color will be applied to all segments except the selected one. To change the background of the selected item you can set the SelectedSegmentBackgroundColor

To set the text color of the strings in the items via the SegmentTextColor property. The color of the selected segment can be set via the SelectedSegmentTextColor property.

You can find an example with the selected color properties in the Selection article.

SDK Browser and QSF applications contain different examples that show RadSegmentedControl's main features. You can find the applications in the Examples and QSF folders of your local Telerik UI for Xamarin installation.
