My controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult OrderDevice(int id)
{
try
{
// TODO: Add insert logic here
orderdevice ord = new orderdevice();
ord.Id = System.Convert.ToInt32(Request.Form["Id"]);
ord.OrderId = System.Convert.ToInt32(Request.Form["OrderId"]);
ord.DeviceId = System.Convert.ToInt32(Request.Form["DeviceId"]);
XMLEntities.AddToorderdevice(ord);
XMLEntities.SaveChanges();
return RedirectToAction("Index");
}
catch
{
return View("Index");
}
}
When post a form I have this error: The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult OrderDevice(Int32)' in 'MvcKVteam.Controllers.ImportXMLController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
How fix it?
