Use route attributes on the Product controller.

Default route

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "{controller=Product}/{action=Index}/{id?}");
});

Action

public class ProductController : Controller
{
    [Route("{id}/{title}")]
    public IActionResult Index(int id, string title, int page)
    {
        return Json(new { id = id, title = title, page = page });
    }
}

URL

https://localhost:44301/2/test?page=1

Results

{
  "id": 2,
  "title": "test",
  "page": 1
}

Use an int constraint.

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "Product",
        pattern: "{id:int}/{title}",
        defaults: new { controller = "Product", action = "Index" });

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

Works for me.  I assume you have other issues with the code.  I assume you are not providing the proper URL to route to the product controller.

I prefer this the route design.

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "Product",
        pattern: "Product/{id:int}/{title}",
        defaults: new { controller = "Product", action = "Index" });

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

Hi MLT111,

What mgebhard did should work well. I guess you have applied paging in your application.And any other configurations would influence your routing.Please share more code which could reproduce your issue.

Best Regards,
