Hi @faresayyad ,

Can you please provide more details:

• Version of ExpressLocalization
• Registered routes
• How do you change the culture? are you using LanguageNavTagHelper
• Can you explain how do you use the code in _Layout?

routeData["culture"] = "{0}"; //how do you use this?

@LazZiya
Thank you for quick response,
Yes, sure:
the app is developed on top of .net core 3.1
1- version is: LazZiya.ExpressLocalization 4.0.0
2- in startup.cs I use endpoints to configure routes:

 app.UseEndpoints(endpoints =>
            {
                endpoints.MapAreaControllerRoute(
                               name: "Admin",
                               "Areas",
                               pattern: "{culture=en}/{area:exists}/{controller=GlobalSettings}/{action}/{id?}");

                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{culture=en}/{controller=Home}/{action=Index}/{id?}");

                endpoints.MapControllers();
                endpoints.MapRazorPages();
            });

** one for areas and the other for default

3- Yes I change the culture using LanguageNavTagHelper, as you mentioned here:
https://github.com/LazZiya/TagHelpers/wiki/LanguageNav-TagHelper-Setup#redirect-to-url

@{ 
    var routeData = ViewContext.RouteData.Values;
    routeData["culture"] = "{0}";
}
<language-nav redirect-to-url="@(Url.RouteUrl(routeData))"></language-nav>

These are the helpers passed to anchor tag:
Update

@faresayyad Looks like you need the routing attributes on the controller:

[Area("Admin")]
[Route("{culture=en}/Admin/[controller]/[action]")]
public class GlobalSettingsController : Controller
{
    // ...
}

---

Additional notices:

• Instead of this:

<a href="..."><localize>Update</localize></a>

You can do this:

<a href="..." localize-content>Update</a>

• Make sure that routeData is defined directly above the <language-nav> tag, otherwise VS will fail to compile the project but will not show an error in the Error List!

Hello,

I would like to reopen the question, please.
One of the cases I faced regarding parameters is like this:

   [Route("{culture}/Properties/Details/{propRefNo?}")]
        public async Task<IActionResult> PropertyDetails(string propRefNo)

as you can see the parameter is of type string. whenever I try to change the language the parameters are gone.
Please refer to the below image marked with red.
