    I am unable to retrieve the Value property of the RadShapeRating object in my xaml either by binding or by retrieving the value in my code behind after a button click event. Also, the ValueChanged event doesn't seem to fire. I'm also unable to look through the RadShapeRating children because the classes are protected. Here is my XAML:

    <?xml version="1.0" encoding="UTF-8"?>
    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" NavigationPage.HasNavigationBar="false" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="Pages.AppointmentRatingPage" Title="Appointment Rating" xmlns:helpers="clr-namespace:Helpers;assembly=AssistForms" BackgroundImage="introbackground.png" xmlns:local="clr-namespace:AssistForms;assembly=AssistForms" xmlns:rating="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.XamarinForms.Input" xmlns:userControls="clr-namespace:CustomControlls;assembly=AssistForms">
        <ContentPage.Resources>
            <ResourceDictionary>
            </ResourceDictionary>
        </ContentPage.Resources>
        <ContentPage.Content>
            <StackLayout Padding="30,100,30,70" HorizontalOptions="Center" VerticalOptions="Center">
                <Frame Padding="3" BackgroundColor="Gray">
                    <StackLayout BackgroundColor="#D3D3D3">
                        <Image Source="mobilefit" Aspect="AspectFit" HeightRequest="35" HorizontalOptions="Start" Margin="5,5,0,0">
                        </Image>
                        <Grid>
                            <Image Source="introbackground.png" Aspect="AspectFill" />
                            <StackLayout VerticalOptions="FillAndExpand" Spacing="10" Padding="5,10,5,5">
                                <Label HorizontalTextAlignment="Center" FontSize="Large" VerticalOptions="Start">Rate your experience at the Y!</Label>
                                <Label HorizontalTextAlignment="Center" FontSize="15" TextColor="White" Text="{Binding Message}"/>
                                <Frame Margin="20,0,20,0">
                                    <StackLayout Padding="20,20,20,50" HorizontalOptions="Center" VerticalOptions="Center" BackgroundColor="White" Spacing="30">
                                        <Label HorizontalOptions="Center" TextColor="#1E90FF" FontSize="18">Choose Your Rating</Label>
                                        <rating:RadShapeRating x:Name="rating" HorizontalOptions="Center"  Value="{Binding RatingValue, Mode=TwoWay}" ValueChanged="Handle_ValueChanged"  ></rating:RadShapeRating>

                                    </StackLayout>
                                </Frame>
                                <StackLayout>
                                    <Button Text="Don't Ask Again" TextColor="White" />
                                    <StackLayout Orientation="Horizontal" VerticalOptions="Start">
                                        <Button Text="Cancel" HorizontalOptions="CenterAndExpand" TextColor="White" Command="{Binding CancelCommand}">
                                        </Button>
                                        <Button Text="Send" HorizontalOptions="CenterAndExpand" TextColor="White" FontAttributes="Bold" Clicked="Handle_Clicked">
                                        </Button>
                                    </StackLayout>
                                </StackLayout>
                            </StackLayout>
                        </Grid>
                    </StackLayout>
                </Frame>
            </StackLayout>
        </ContentPage.Content>
    </ContentPage>

     

    Here is my code behind:

    using System;
    using Xamarin.Forms;
    using ViewModels;
    using AssistForms;


    namespace Pages
    {
        public partial class AppointmentRatingPage : ContentPage
        {
            void Handle_ValueChanged(object sender, Xamarin.Forms.ValueChangedEventArgs e)
            {
                throw new NotImplementedException();
            }



            void Handle_Clicked(object sender, System.EventArgs e)
            {
                foreach (var child in rating.Children)
                {
                    var childChild = child.BackgroundColor;
                    //Telerik.XamarinForms.Input.RatingItem childRating = rating as Telerik.XamarinForms.Input.RatingItem;
                    //  var backgroundCole = child.
                    //RatingItem ratingItem = child as RatingItem;
                }
            }



            public string NavigationPageName { get; set; }


            public AppointmentRatingViewModel ViewModel
            {
                get;
                set;
            }



            public AppointmentRatingPage(AppointmentRating appointmentRating)
            {

                InitializeComponent();

                NavigationPage.SetHasNavigationBar(this, false);
                App.MasterDetailPageProperty.IsGestureEnabled = false;

                NavigationPageName = "AppointmentRating";

                ViewModel = new AppointmentRatingViewModel(appointmentRating);

                BindingContext = ViewModel;


            }



            protected override void OnAppearing()
            {
                base.OnAppearing();
            }

        }
    }
