Filtering on loadData using POST request

Question

The grid is not filtered when I use POST request

loadData: function (filter) {
  return $.ajax({
  type: "POST",
  url: "frmNewGroup.aspx/searchFilter",
  data: JSON.stringify(filter),
  contentType: "application/json; charset=utf-8",
  success: function (data) {
     console.log(data);
    }
  });
}

Do we have to use GET request?

Thanks.

You missed def.resolve(data); when you get data from ajax.

loadData : function(filter) {
        var def = $.Deferred();
        $.ajax({
           type: "POST",
          url: "frmNewGroup.aspx/searchFilter",
          data: JSON.stringify(filter),
          contentType: "application/json; charset=utf-8",
        }).done(function(data) {
            console.log(data);
            def.resolve(data);
        });
        return def.promise();
    }
