2         <wt:combobox field="@Model.AllshippingmethodsID" items="Allshippingmethods" multi-select="true" />

2         public IActionResult GetServicenameIDByshippingmethod(Guid id)
3         {
4            var vm= DC.Set<ShippingMethod>().Where(c => c.ServicenameCodeID == id).Select(m=> new { Text=m.cnname,Value=m.ID}).ToList();
5             
6             return Json(vm);
