[httppost] [validateantiforgerytoken] public jsonresult editcontact(contactdto contact) {     if (customvalidation(code) && modelstate.isvalid)     {         _dbmanager.createcode(code);          //return redirecttoaction("details", "counterparties", new { id = code.codecounterpartyid });         return json(new { data = "ok" }, jsonrequestbehavior.allowget);     }      return json(new { data = "nok" }, jsonrequestbehavior.allowget); }

modal ajax:

@using system.globalization @model updatetabs.models.contactdto  <div id="editcontactmodaldiv" class="modal fade" role="dialog">     <div class="modal-dialog modal-lg">      .......          @using (ajax.beginform("editcontact", "home", new ajaxoptions { httpmethod = "post", onsuccess = "validatekeys"}, new { id = "formcreatecontact" }))         {             @html.antiforgerytoken()             @html.validationsummary(false, "", new { @class = "text-danger" })              ......              @html.textboxfor(m => m.name)             <br/>             @html.validationmessagefor(m => m.name)              ......               }         .......      </div> </div>

and jquery part:

function validatekeys(result) {     if (result.ok) {         $('#createcodemodaldiv').modal('hide');     } else {          alert("model invalid !");         $('#createcodemodaldiv').modal('show');     } }
