Tizen Developers

Hi Jaehong Park,
There are some limitations to NavigationPage, but we are supporting it on Tizen wearable profile.
When I check NavigationPage.TitleView on Tizen 5.0 wearable emulator with the following code, it works.
Could you check it again or share the sample code you used with us?
Thanks.

public App()
{
    InitializeComponent();
    MainPage = new NavigationPage(new Navi.MainPage());
}

MainPage.xaml

<?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="Navi.MainPage">
    <NavigationPage.TitleView>
        <Label Text="Title Label"
               HeightRequest="80" 
               HorizontalTextAlignment="Center"
               VerticalTextAlignment="Center"
               TextColor="Black"
               BackgroundColor="Aqua"/>
    </NavigationPage.TitleView>
    <ContentPage.Content>
        <StackLayout>
            <Label Text="Welcome to Xamarin.Forms!"
                   VerticalOptions="CenterAndExpand"
                   HorizontalOptions="CenterAndExpand" />
            <Button Text="Next Page"
                    Clicked="Button_Clicked"/>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

MainPage.xaml.cs

private async void Button_Clicked(object sender, EventArgs e)
{
    await Navigation.PushAsync(new SecondPage());
}

SecondPage.xaml

<?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="Navi.SecondPage"
             Title="SecondPage">
    <ContentPage.Content>
        <StackLayout BackgroundColor="HotPink">
            <Label Text="Second!"
                   VerticalOptions="CenterAndExpand" 
                   HorizontalOptions="CenterAndExpand" />
        </StackLayout>
    </ContentPage.Content>
</ContentPage>
