Renderer

public class SegmentedControlRenderer : NativeRenderer
	{
		protected override void OnModelSet(VisualElement model)
		{
			base.OnModelSet (model);

			SegmentedControlView segmentedControlView = (SegmentedControlView)this.Model;

			var native = new UISegmentedControl ();
			native.Frame = new RectangleF (20, 20, 280, 40);
			// Create the view using the properties from the model.
			native.InsertSegment ("One", 0, false);
			native.InsertSegment ("Two", 1, false);
			native.SelectedSegment = segmentedControlView.SelectedItem;

			native.ValueChanged += (s, e) => {
				var ctrl = s as UISegmentedControl;
				segmentedControlView.SelectedItem = ctrl.SelectedSegment;
			};




			// Add it as a child to this view by setting it as the control
			// for this renderer.
			SetNativeControl (native);
		}

public class SegmentedControlView : BoxView

		public static readonly BindableProperty SelectedItemProperty = 
			BindableProperty.Create<SegmentedControlView,int> (

		public int SelectedItem {
			get { return (int)GetValue (SelectedItemProperty); }
			set {

				SetValue (SelectedItemProperty, value); 
			}
