Visual Studio .NET - mvc lambda expression - Asked By raj on 30-Dec-16 07:19 AM

i am trying to use edit in mvc application by using the code

      public ActionResult edit(int id)
        itembusinesslayer itmbl1 = new itembusinesslayer();
        itlist items1 = itmbl1.itemlist.SingleOrDefault(sss => sss.itemcode == id);

        return View(items1);

but it throws the below error:

The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult edit(Int32)' in 'ItemMaster.Controllers.ItemController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters

how to solve this issue. not able to proceed further
