jquery - ASP.Net MVC ViewBag is not working on functions which are called by AJAX -

i have implemented function delete record db table. if there error, want pass in viewbag. viewbag value not passed view.

controller

[httppost]     public actionresult deleterecord(string name)     {         try         {             if (!(string.isnullorempty(name)))             {                 driver_tab driver = db.driver_tab.singleordefault(m => m.name == name);                 db.driver_tab.remove(driver);                 db.savechanges();                 viewbag.msg = "1";                 messagebox.show(viewbag.msg);                 return view("main");             }             else             {                 viewbag.msg = "2";                 return view("main");             }         }         catch (dbentityvalidationexception ex)         {             viewbag.msg = ex.message.tostring();             return view("main");         }         catch (exception ex2)         {             viewbag.msg = ex2.message;             return view("main");         }     } 

ajax function in view

function deleteselectedrecord() {     var selectedname = $("#lstitems").val()     $.ajax({         url: 'deleterecord',         method: "post",         data: { name: selectedname }     }).done(function () {         $("#lstitems").empty();         search();         getcount();         $('#modaldeleted').modal('show');         settimeout(function () { $('#modaldeleted').modal('hide'); }, 2000);     }); } 

i use viewbag.msg in view <h2>@viewbag.msg not working. problem in code.

if there error occurred in controller after executing delete function, want pass message view , display it. how accomplish that..?

you're ajax not using response deleterecord. contains rendered view html, including viewbag data.

you need update javascript use response, looking @ code believe needs populate modal displaying:

something like:

$.ajax({   url: 'deleterecord',   method: "post",   data: { name: selectedname } }).done(function (data) {   // response data, example:   $('#modaldeleted').html(data); });
