I need to pass parameter between page but Programmatic Navigation with a Pack URI (https://learn.microsoft.com/en-us/dotnet/framework/wpf/app-development/navigation-overview#programmatic-navigation-with-a-pack-uri)

Note: I don't want to use the constructor to pass the parameter

Currently I do this:

 Uri uri = new Uri("AnotherPage.xaml", UriKind.Relative);
        this.NavigationService.Navigate(uri, parameter);

but once again microsoft forgot to put an example on how to receive the data in the other page.

I try this in the second page to receive the parameter:

private void Page_Loaded(object sender, RoutedEventArgs e)
    {
        NavigationService.LoadCompleted += NavigationService_LoadCompleted;
    }

    private void NavigationService_LoadCompleted(object sender, NavigationEventArgs e)
    {
        throw new NotImplementedException();
    }

but it's not working.

In this post (How to pass values (parameters) between XAML pages?) in the second point use

example: 2. Using NavigationEventArgs

protected override void OnNavigatedFrom(NavigationEventArgs e)
{
    // NavigationEventArgs returns destination page
    Page destinationPage = e.Content as Page;
    if (destinationPage != null) {

        // Change property of destination page
        destinationPage.PublicProperty = "String or object..";
    }
}

but OnNavigatedFrom doesn't exist

In this post use a global variable like(How to pass values between two pages in WPF)

string myText = (string)Application.Current.Properties["test"];

maybe this is the solution if there does not exist a better way

here (Passing data between pages in wpf) no example

I don't know maybe I'm missing something about WPF Navigation (https://learn.microsoft.com/en-us/dotnet/framework/wpf/app-development/navigation-overview) Can someone point me in the right direction or am I just wasting my time and this is impossible to do.

I'm sorry for my English, I don't speak

  • Won't it be easy if you setup a separate singleton class to store data from first page and on loading the second page lookup the data? – Lingam Oct 30 '19 at 05:53
