Hi Ladies and Guys,

I'm new to the forum. I'm working on an ASP.NET Core Razor Pages app. It's a CRUD. I was already able to implement Create and Edit in the same Razor page. I have a list of products (in Index.cshtml) and after the model fields on each row I have buttons for Edit and Delete. What I want is that when I click the Delete button, appears the bootstrap Modal and if I click the Confirm button in it, the C# POST method that is in the same Index page deletes the row (and the row in the DB). I took from Internet some Javascript and the Modal appears, but when I click the confirm button, the C# method is not called and the VS Debugger shows Model.productos in:

@foreach (var producto in Model.productos) { // here go the rows }

as null (NullReferenceException), only productos, not Model.

Here are the relevant files in where the problem is.

First, the Index.cshtml.cs

namespace CrudProductos.Pages.Productos
{
    public class IndexModel : PageModel
    {
        private readonly ApplicationDBContext _context;
        public IList productos { get; set; }

        public IndexModel(ApplicationDBContext context)
        {
            _context = context;
        }

        public void OnGet()
        {
            productos = _context.Producto.ToList();
        }

        public IActionResult OnPostDeleteConfirm(int id)
        {
            Producto Producto = _context.Producto.Find(id);
            if (Producto == null)
            {
                return NotFound();
            }
            _context.Producto.Remove(Producto);
            _context.SaveChanges();
            return RedirectToPage("Index");
        }

    }
}

And the Index.cshtml

@page
@model CrudProductos.Pages.Productos.IndexModel
@{
    ViewData["Title"] = "Lista de Productos";
}


Lista de Productos


Agregar Nuevo Producto


    @foreach (var producto in Model.productos)
    {
        
        }
    

    
        

            Id
            Nombre
            Precio
            Stock
            Fecha Creación
            Acciones
        

    
    

            @producto.Id
            @producto.Nombre
            @producto.Precio.ToString("C")
            @producto.Stock
            @producto.FechaCreación
            
                Editar
                
                Detalle
            
        










    



@section Scripts {
    
}

Any help is appreciated. If you need more information about this topic, please let me know. Thanks
