ASP.NET MVC AJAX call return Error Message in parallel with Partial View -

the scenario in asp.net mvc (4,5) maxing ajax call returns partial view. based on different situations may need return error message - display user example..

my current approach this.

in js:

$.ajax({     url: url,     type: "post",     data:{ id: id},     success: function (response) {         $("#container").html(response);     },     error: function (er) {          if (er.status == "405")             {// someth }         else if (er.status == "406")                 {// someth else }     } }); 

in controller:

public actionresult servermethod(int id) {     if (id = 0)         return new httpstatuscoderesult(405);     if (id = 1)         return new httpstatuscoderesult(406);      //otherwise..      return partialview("view", model); }    

i aware hack , not proper solution.. there better way of doing this?

you return jsonresult in fail cases. add properties want json.

something this:

public actionresult servermethod(int id) {     if (id == 0)     {         return json(new         {             failed = true,             failtype = "type1", // whatever makes sense             //otherrelevantproperty = whatever         });     }      if (id == 1)     {         return json(new         {             failed = true,             failtype = "type2", // whatever makes sense             //otherrelevantproperty = whatever         });     }      //otherwise..      return partialview("view", model); }    

in ajax call this:

$.ajax({     url: url,     type: "post",     data:{ id: id},     done: function (response) {         if (response.failed) {             // switch response.failtype , use relevant             // json properties created in controller         }         else {             $("#container").html(response);         }     } }); 

if absolutely need return failed status code, set before returning json such as:

if (id == 0) {     response.statuscode = 500;      return json(new     {         failed = true,         failtype = "type1", // whatever makes sense         //otherrelevantproperty = whatever     }); } 

and handle failed case in fail callback:

$.ajax({     url: url,     type: "post",     data:{ id: id},     done: function (response) {         $("#container").html(response);     },     fail: function(xhr) {         var response = json.parse(xhr.responsetext);         if (response.failed) {             // switch response.failtype , use relevant             // json properties created in controller         }     } }); 

please note haven't tested particular code , demonstration only. am, however, using similar set-up in projects.
