</StackLayout>

but i swap the image this way

if (CorIndicador == "VERDE")
    image.Source = ImageSource.FromResource("Operacional.Images.faturamento-03.png");
else
{
     var pinta = CorIndicador == "VERMELHO" ? image.Source = ImageSource.FromResource("Operacional.Images.faturamento caixa-26.png") : image.Source = ImageSource.FromResource("Operacional.Images.faturamento-02.png");
}

the issue is when i tap the image nothing happens. Before, when i had other image inside a boxview worked. I changed boxview to an image that ocuupy all cell(row/column) and now not work. PS: i have no error. I putted a break point and doesn't break at point.

I forgot code behind. This is my TappedGesture

     async void OnTapGestureReconizerTapped(object sender, EventArgs e)
            {
                PainelB2B p = new PainelB2B
                {
                    IdPainel = (int)TipoIndicador.Faturamento,
                    Nome = "Faturamento"
                };

                await Navigation.PushModalAsync(new VisualizadorPainel(p));
            }
