when using asp.net mvc json result return , in internet explorer , save as json file option will come.

this can be resolved by

 
// this was previous
//  return Json(new { sView = msg, IsSuccess = isnsuccs }, JsonRequestBehavior.AllowGet);
// this is chnaged 
                    return Json(new { sView = msg, IsSuccess = isnsuccs }, "text/plain", System.Text.Encoding.UTF8,
                        JsonRequestBehavior.AllowGet);

in json success , have to parse as json .

var nres = $.parseJSON(context);
