// Xamarin.Forms.Forms.Init(this, bundle);

var layout = new GridLayout();
layout.Columns.Add(100);
layout.Columns.Add(100);
layout.Spacing = 10;
this.RootGrid.Children.Add(layout);

var dataContext = new MyDataContext();

// Create a collection view source
var collectionViewSource = new CollectionViewSource(dataContext);
collectionViewSource.Source = dataContext.MyList;

// Create a collection view
var collectionView = new CollectionView(collectionViewSource);
collectionView.ItemTemplate = new MyItemTemplate(dataContext);
layout.Children.Add(collectionView);

// Add a button to add new items to the collection
var addButton = new Button();
addButton.Text = "Add item";
addButton.Clicked += (sender, e) => {
    var newItem = new MyItem() { Name = "New item", Description = "Description for new item" };
    dataContext.MyList.Add(newItem);
};
layout.Children.Add(addButton);
