Getting Started with Custom Picker for Xamarin

This article will guide you through the steps needed to add a basic RadTemplatedPicker 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:

If you don't want to add the all Telerik.UI.for.Xamarin nuget package, you have the option to add a separate nuget package. For RadTemplatedPicker control you have to install the Telerik.UI.for.Xamarin.Input nuget package. This nuget will automatically refer the Telerik.UI.for.Xamarin.Primitives, Telerik.UI.for.Xamarin.Common, and Telerik.UI.for.Xamarin.DataControls nuget packages.

  • Add the references to Telerik assemblies manually, check the list below with the required assemblies for RadTemplatedPicker component:
Platform Assemblies
Portable Telerik.XamarinForms.Input
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Primitives.dll
Telerik.XamarinForms.SkiaSharp.dll
Android Telerik.XamarinForms.Input
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Primitives.dll
Telerik.XamarinForms.SkiaSharp.dll
iOS Telerik.XamarinForms.Input
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Primitives.dll
Telerik.XamarinForms.SkiaSharp.dll
UWP Telerik.XamarinForms.Input
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Primitives.dll
Telerik.XamarinForms.SkiaSharp.dll

3. Adding RadTemplatedPicker control

You could use one of the following approaches:

Drag the control from the Toolbox.

Take a look at the following topics on how to use the toolbox:

Create the control definition in XAML or C#.

The snippet below shows a simple RadTemplatedPicker definition:

<telerikInput:RadTemplatedPicker>
    <telerikInput:RadTemplatedPicker.SelectorTemplate>
        <ControlTemplate>
            <telerikInput:RadCalendar SelectedDate="{TemplateBinding SelectedValue, Mode=TwoWay}"/>
        </ControlTemplate>
    </telerikInput:RadTemplatedPicker.SelectorTemplate>
</telerikInput:RadTemplatedPicker>
RadTemplatedPicker templatedPicker = new RadTemplatedPicker();
ControlTemplate controlTemplate = new ControlTemplate(typeof(TemplatedPickerCalendar));
templatedPicker.SelectorTemplate = controlTemplate;

In addition to this, you need to add the following namespace:

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

This is the result:
