How to Get the Value from ItemSource Binding in Listview?

Hi,

  I created the Listview using Xamarin.Forms. I could get the data in exploreList (Observable collection) and assign to ItemSource. So I can bind the value to Cell controls like Label using SetBinding. But some case I need to get the string data instead of Binding. Because I created the **Rating star** view in separate Layout class and included as one of children in Listview grid. So I need to pass the string Parameter.  Please someone help me. Thanks in advance.

exploreListView = new ListView
{
RowHeight=100,

            ItemsSource = exploreList,
            ItemTemplate = new DataTemplate(() =>
                {

                    Grid gridShop = new Grid {
                        Padding=5,
                        BackgroundColor=Color.Gray,
                        VerticalOptions = LayoutOptions.Fill, RowSpacing=7,
                        RowDefinitions = 
                        {
                            new RowDefinition { Height = GridLength.Auto },
                            new RowDefinition { Height = GridLength.Auto },
                            new RowDefinition { Height = GridLength.Auto }
                        },
                        ColumnDefinitions = 
                        {
                            new ColumnDefinition { Width = new GridLength(70, GridUnitType.Absolute)                    },
                            new ColumnDefinition { Width = GridLength.Auto },                                                    
                        }
                        };


                    Image shopImage = new Image
                    {
                        WidthRequest=70, HeightRequest=70,
                        //Source = ImageSource.FromFile("NoPhoto_PH.png"),
                        VerticalOptions = LayoutOptions.CenterAndExpand,
                        Aspect = Aspect.AspectFill
                    };


                    Label statuslabel = new Label
                    {
                        //Text ="Now Opening",
                        Font = Font.SystemFontOfSize(NamedSize.Small),
                        VerticalOptions = LayoutOptions.CenterAndExpand,
                    };


                    Label Shoplabel = new Label
                    {
                        //Text ="Virgin Mega Store",
                        Font = Font.SystemFontOfSize(NamedSize.Medium),
                        VerticalOptions = LayoutOptions.StartAndExpand,

                    };







                ** RatingStar ratingStar = new RatingStar (“4”); // Need to pass the value**








                    //string logoUrl = Constants.b2oImageServer + "/images/shops/"+shopId+"/logo/"+logoUrl;

                    shopImage.SetBinding(Image.SourceProperty, new Binding("logoPath"));
                    statuslabel.SetBinding(Label.TextProperty,  new Binding("openStatus"));
                    Shoplabel.SetBinding(Label.TextProperty, new Binding("shopNameEn"));

                    gridShop.Children.Add(shopImage,0,1,0,2);
                    gridShop.Children.Add(statuslabel,1,0);
                    gridShop.Children.Add(Shoplabel,1,1);
                    gridShop.Children.Add(ratingStar,1,2);

                    //======== make view Cell =========
                    return new ViewCell()
                    {
                        View = gridShop
                    };
                })
        };
