  Value passed by session from method to another does not work!

  May 14, 2020 08:27 AM|musbah7@hotmail.com|LINK

  Hi

  I have tow query type models that I want to get their data by ajax in one view with Entity Framework Core.

  I'm trying to pass the number of records returned by Ajax to the caller view by session, But no value returned.

  All view which I tried to return number of records returned by Ajax (@ViewBag.A):

  <form>
     <div class="col-xs-2">
         <label for="ex2">Id</label>
         <input class="form-control" type="text" id="sidd" name="sid">
     </div>
     <input type="button" value="بحث" id="search" class="btn btn-default">
  </form>
  
  <div>
      <ul class="nav nav-tabs" style="color:black;">
          <li class="in active" style="color:black;"><a data-toggle="tab" href="#home">@ViewBag.A Actions</a></li>
          <li><a data-toggle="tab" href="#menu1" style="color:black;">Holidays</a></li>
      </ul>
      @*Some code*@
      <div class="tab-content" id="col-md-12">
          <div id="home" class="tab-pane fade in active">          
              <table class="table">
                  <thead>
                      <tr>
                          <th>
                              Id
                          </th>
                          <th>
                              Name
                          </th>
                      </tr>
                  </thead>
                  <tbody id="ActionsEtags"></tbody>
              </table>
          </div>
      </div>
  </div>
  @section Scripts {
      @{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
  
      <script>
          $(function () {
              $('#search').on('click', function () {
                  var sid = $('#sidd').val();
                  $.ajax({
                      type: "GET",
                      url: "/MyController/ActionsHeaderE?sid=" + sid,
                      success: function (data) {
                          $("#ActionsEtags").empty();
                          $.each(data, function (index, item) {
                              console.log(item);
                              $('<tr id="Row' + index + '">' +
                                  '<td>' + item.Id + '</td>' +
                                  '<td>' + item.Name + '</td>' +
                                  '</tr>').appendTo($('#ActionsEtags'));
                          });
                      }
                  });
              });
          });
      </script>
  }

  But when I pressed Search button the records are returned successfully but with blank space of number of records Why? and How to solve please?

  Hi musbah7@hotmail.com ,

  According to the calling logic between All view and ActionsHeaderE view , you call the All action firstly  and the session value is null at this time . And then use ajax to call the  ActionsHeaderE  action  to set the session value. The return data of the success function in ajax is only the data list from database, not contain the session and call the All action again.

  If you want to get  number of records from ajax , you could refer to below:

   success: function (data) {
                      var a = Object.keys(data).length;
                      $('a[href^="#home"]').html(a + " Actions");
                      $("#ActionsEtags").empty();
                      $.each(data, function (index, item) {
                          console.log(item);
                          $('<tr id="Row' + index + '">' +
                              '<td>' + item.Id + '</td>' +
                              '<td>' + item.Name + '</td>' +
                              '</tr>').appendTo($('#ActionsEtags'));
                      });
                  }

  Best Regards,

  Sherry
