Html.Beginform error with area

Question

I have a view with the following form:

@using (Html.BeginForm("Salva", "Blog", new { area = "admin" }, FormMethod.Post, false, new { id = "formCadastro" }))

However, when clicking on Ubmit the url that appears is the following

• http://localhost:1378/Blog/Saved? area=admin

But I need her to show up like this:

• http://localhost:1378/Admin/Blog/Save

My mapping is as follows:

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

            endpoints.MapAreaControllerRoute(
                name:"Admin",
                areaName: "Admin",
                pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}");
        });

But I’ve used it too:

app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");
            endpoints.MapControllerRoute("Admin", "{controller=Home}/{action=Index}/{id?}");
        });

Answer 1

When using Asp.net Core avoid using the framework Taghelpers. Instead use the new Razor syntax, which makes the code clearer and more stable.

Ex:

<form asp-controller="blog" asp-action="salva" asp-area="admin" method="post" id = "formCadastro">
    <!-- Input and Submit elements -->
</form>

This article explains in detail how to use the new syntax.
