function UserIdChange(evt, ui) {

                 var UserId = ui.items[0].data.Value; //Passing selected value to the controller and retriving json object
                 $.getJSON('GetUserData', { id: UserId}, function (data) {


                     var name_editor = $("#gridUserInformation").igGridUpdating("editorForKey", "Name");
                     name_editor.igTextEditor("value", data[0]);

                     var occupation_editor = $("#gridUserInformation").igGridUpdating("editorForKey", "Occupation");
                     occupation_editor.igTextEditor("value", data[1]);
