Getting Started with the .NET MAUI CollectionView
This guide provides the information you need to start using the Telerik UI for .NET MAUI CollectionView by adding the control to your project.
At the end, you will achieve the following result.
Prerequisites
Before adding the CollectionView, you need to:
Define the Control
1. When your .NET MAUI application is set up, you are ready to add a CollectionView control to your page. The following example shows a sample CollectionView definition populated with sample data:
2. Define the RadCollectionView in XAML:
<telerik:RadCollectionView x:Name="collectionView"
ItemsSource="{Binding Locations}"
DisplayMemberPath="City">
<telerik:RadCollectionView.BindingContext>
<local:ViewModel />
</telerik:RadCollectionView.BindingContext>
</telerik:RadCollectionView>
var collectionView = new RadCollectionView
{
ItemsSource = new ViewModel().Locations,
DisplayMemberPath = "City"
};
3. Add the telerik namespace:
xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"
4. Create sample DataModel:
public class DataModel : NotifyPropertyChangedBase
{
private string continent;
private string country;
private string city;
private int id;
public string Continent
{
get => this.continent;
set => this.UpdateValue(ref this.continent, value);
}
public string Country
{
get => this.country;
set => this.UpdateValue(ref this.country, value);
}
public string City
{
get => this.city;
set => this.UpdateValue(ref this.city, value);
}
public int Id
{
get => this.id;
set => this.UpdateValue(ref this.id, value);
}
}
5. Define the ViewModel class:
public class ViewModel : NotifyPropertyChangedBase
{
public ViewModel()
{
this.Locations = new ObservableCollection<DataModel>
{
new DataModel { Continent = "Europe", Country = "Austria", City = "Graz", Id = 1 },
new DataModel { Continent = "Europe", Country = "Austria", City = "Innsbruck", Id = 2 },

public ObservableCollection<DataModel> Locations { get; set; }
}
5. Register the Telerik controls through the Telerik.Maui.Controls.Compatibility.UseTelerik extension method called inside the CreateMauiApp method of the MauiProgram.cs file of your project:
using Telerik.Maui.Controls.Compatibility;
public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();
builder
.UseTelerik()
.UseMauiApp<App>()
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
});
return builder.Build();
}
}
