I am trying to display login player `FullName` in the top right of the navigation bar. In may Xamarin Forms app, I am using tabbed pages to display Home, Map, Settings, Daily Count tabs created via code ( don't have separate navigation.xaml). 
Below is Home screen, would like to display the name in the space where I have marked in the screenshot.

In the `GetLoginPlayerName()` method I can see `details` is assigned to `loginPlayer.Text = details.ToString()`, but still I am unable to see player FullName in the navigation space. Could some one please advise how can I fix this ? 

Below is the Home.xaml

```xml
    <?xml version="1.0" encoding="utf-8" ?>
    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"  
                 xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"  
                 x:Class="soccerapp.Home" BackgroundColor="White" Title="Home">
    <NavigationPage.TitleView>
        <StackLayout Orientation="Horizontal" BackgroundColor="#D60000">        
            <Label x:Name="loginPlayer" VerticalTextAlignment="Center"/>
        </StackLayout>
    </NavigationPage.TitleView>
        <ContentPage.Resources>
            <DataTemplate x:Key="playerTemplate">
                <ContentView>
                    <StackLayout  Margin="5,5" BackgroundColor="LightGreen">
                        <Label Text="{Binding FullName}"/>
                        <Label Text="{Binding Mobile}"/>
                        <Label Text="{Binding SoccerPosition}"/>
                        <Button Text="Remove Player"  Clicked="DeleteButton_OnClicked" WidthRequest="120" HeightRequest="50"  TextColor="White" BackgroundColor="OrangeRed"></Button>
                    </StackLayout>
                </ContentView>
            </DataTemplate>
        </ContentPage.Resources>
        <StackLayout Margin="5">
            <CollectionView x:Name="collectionview"
             ItemTemplate="{StaticResource playerTemplate}">
                <!--span here decides the number of items shows in one line. Now is 3 items one line-->
                <CollectionView.ItemsLayout>
                    <GridItemsLayout Orientation="Vertical" Span="3" />
                </CollectionView.ItemsLayout>
            </CollectionView>
        </StackLayout>
    </ContentPage> 

```

See the below code in Home.xaml.cs

```cs
    namespace soccerapp
    {
        [XamlCompilation(XamlCompilationOptions.Compile)]
        public partial class Home : ContentPage
        {
            public SQLiteConnection conn = null;
            ObservableCollection<PlayerDetails> players;
            string loginEmail;

            public Home(string email)
            {
                InitializeComponent();
                conn = DependencyService.Get<Isqlite>().GetConnection();
                conn.CreateTable<PlayerDetails>();
                players = new ObservableCollection<PlayerDetails>();
                collectionview.ItemsSource = players;
                loginEmail = email;
                GetLoginPlayerName();
                DisplayDetails();
            }

            public void GetLoginPlayerName()
            {
                int count = (from x in conn.Table<PlayerDetails>().Where(x => x.Email == loginEmail) select x).Count();
                if (count!= 0)
                {
                    var details = (from x in conn.Table<PlayerDetails>()
                                   where x.Email == loginEmail
                                   select new
                                   {
                                       Name = x.FullName

                                   }).ToList();
                    loginPlayer.Text = details.ToString();

                }

            }

            public void DisplayDetails()
            {
                List<PlayerDetails> details = (from x in conn.Table<PlayerDetails>() select x).ToList();
                for (int i = 0; i < details.Count; i++)
                {
                    players.Add(details[i]);
                }

            }

        }
    }
