UWP button not firing event

Question

I m working on a UWP project. I have two buttons to go from one page to another one. But I don't understand why the button is never called, I try different tutorials and technique it doesn't work.

<Page
    x:Class="MultiplatformMvvm.UWP.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MultiplatformMvvm.UWP"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">
    <Page.Resources>
        <ResourceDictionary>

            <Style x:Key="textBlockStyle" TargetType="TextBlock">
                <Setter Property="Margin" Value="12,20,12,12"/>
                <Setter Property="HorizontalAlignment" Value="Center"/>
                <Setter Property="FontSize" Value="24"/>
            </Style>

            <Style x:Key="buttonStyle" TargetType="Button">
                <Setter Property="Margin" Value="12"/>
                <Setter Property="HorizontalAlignment" Value="Center"/>
                <Setter Property="Background" Value="Purple"/>
                <Setter Property="Foreground"  Value="White"/>
            </Style>

        </ResourceDictionary>
    </Page.Resources>

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <StackPanel>
            <TextBlock Text="Un café !" Style="{StaticResource textBlockStyle}"/>
            <Button x:Name="coffeeButton" Style="{StaticResource buttonStyle}" >
                Go Coffee
            </Button>
            <Button x:Name="myContactsButton" Style="{StaticResource buttonStyle}">
                My contacts
            </Button>
        </StackPanel>
    </Grid>
</Page>

My C# code :

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        InitializeComponent();
        coffeeButton.Click += coffeeButton_Click;
    }

    void coffeeButton_Click(object sender, RoutedEventArgs e)
    {
        // I never enter here
        Frame.Navigate(typeof(CoffeeListPage));
    }

    private void myContactsButton_Click(object sender, RoutedEventArgs e)
    {
        // I never enter here
        Frame.Navigate(typeof(ContactListPage));
    }
}

Answer 1

Have you tried: - Attaching a handler to the button in xaml itself and see it that works? - In case you are using Bindings, then adding a command binding?

Also in your scenario,try this: In your constructor after the InitializeComponent(); add:

Loaded += (s, e) => { coffeeButton.Click += coffeeButton_Click; };

see if that works.

I finally clean all the cache in the UWP project and rebuild and it finally works. Hope it helps someone.
