I have a Remote attribute on the ProductCode property of  Product model. When I create a new Product it works perfect  and tells the user  that an ProductCode is already in use. Now I'm having a problem in my editing form (if the user wants to updates values). It tells the user that his/her ProductCode is already in use, I don't want it to give that message at edit mode . How can I restrict the Remote attribute to behave in Edit mode? i searched but didnt get proper solution...

In the View Add Hidden field

C#

@Html.Hidden(initialProductCode, Model.ProductCode)

In the Remote attribute Add AdditionalFields

C#

[Remote("ValidateProductcode", "Controller", ErrorMessage = "Product Code already exists.", AdditionalFields = "initialProductcode")]

and the Controller action function

C#

public JsonResult ValidateProductcode(string Productcode, string initialProductcode)
{
  try
  {
      if (Productcode == initialProductcode)
      {
          return Json(true, JsonRequestBehavior.AllowGet);
      }
      var Productcode = datacontext.tablename.Single(m => m.ProductCode == Productcode);
      return Json(false, JsonRequestBehavior.AllowGet);
  }
  catch (Exception)
  {
      return Json(true, JsonRequestBehavior.AllowGet);
  }
}
