Hi
I am stuck, using datatable editor.

I send the data to the controller to minupulate them in a stored procedure. I get them through HttpContext.Current.Request but when I want to return to the datatable with the updater data I don't know how to return them. If request.Form or how to update what I edit in the datatable

is my code

[HttpPost]
public async Task<ActionResult> ActualizaDescuentos(string PriceGroupId, string Recurso)
{

        try
        {
            var ObtenerUsuario = Session[LigadoDeUsuario.LlaveInterna].ToString();
            var dato = ObtenerUsuario.Split(':');
            var usuario = dato[0];

            var request = System.Web.HttpContext.Current.Request;
            var list = new List<KeyValuePair<string, string>>();

            if (request.Form != null)
            {
                foreach (var key in request.Form.AllKeys)
                {
                    list.Add(new KeyValuePair<string, string>(key, request.Form[key]));
                }
            }
            DataUpdateRecursos dataUpdateRecursos = new DataUpdateRecursos();
            dataUpdateRecursos.InventDimId = "Axapta";
            dataUpdateRecursos.PriceDiscItemRelation = Recurso;
            dataUpdateRecursos.DiscountType = list[0].Value;
            dataUpdateRecursos.AmountCur = Convert.ToDecimal(list[1].Value);
            dataUpdateRecursos.AmountQty = 0;
            dataUpdateRecursos.Importe = Convert.ToDecimal(list[1].Value);
            dataUpdateRecursos.Cascada = Convert.ToInt32(list[3].Value);
            dataUpdateRecursos.Secuencia = Convert.ToInt32(list[4].Value);
            dataUpdateRecursos.Factura = list[5].Value;
            dataUpdateRecursos.Usuario = usuario;
            dataUpdateRecursos.Cuenta = Convert.ToInt32(list[6].Value);
            dataUpdateRecursos.PriceGroupId = PriceGroupId;

          return Json(request);

        }
        catch (Exception ex)
        {
            return Json("error" + ex);
        }
