How to navigate to another wpf page

Question

So I tried to navigate to another wpf page but it doesn't work at all. Here's what I've been using:

C#:

    private void btnNext_Click(object sender, RoutedEventArgs e)
    {
        Doelen nextPage = new Doelen();
        this.NavigationService.Navigate(nextPage);
    }

XAML:

    <Button x:Name="btnNext" Content="Volgende" Margin="0,10,0,0" Click="btnNext_Click"/>

The big problem here is that Visual Studio says that there is no Navigate in NavigationService .

Can anyone tell me what I`m doing wrong?

For full code see picture below:

Answer 1

I would suggest using the this pointer and be explicit on your routedeventargs.

    using System.Windows.Navigation;

within:

public partial class MyPage : Page


private void btnNext_Click(object sender, System.Windows.RoutedEventArgs e)
{
    Doelen nextPage = new Doelen();
    NavigationService.Navigate(nextPage);
}

Answer 2

NavigationWindow nw = new NavigationWindow();
nw.Content = new Doelen();
nw.ShowDialog();

or nw.Show():

you may need a nw.Initialze();
