Hi,

WebService (Plant class see in source code of https://examples1.ext.net/#/Form/Com...Custom_Search/)

[WebMethod]
        public Paging<Plant> PlantsPaging(int start, int limit, string sort, string dir, string filter)
        {
            List<Plant> plants = Plant.TestData;
            if (!string.IsNullOrEmpty(filter) &amp;&amp; filter != "*")
            {
                plants.RemoveAll(plant => !plant.Common.ToLower().Contains(filter.ToLower()));
            }

            if (!string.IsNullOrEmpty(sort))
            {
                plants.Sort(delegate(Plant x, Plant y)
                {
                    object a;
                    object b;

                    int direction = dir == "DESC" ? -1 : 1;

                    a = x.GetType().GetProperty(sort).GetValue(x,null);
                    b = y.GetType().GetProperty(sort).GetValue(y, null);

                    return CaseInsensitiveComparer.Default.Compare(a, b) * direction;
                });
            }

            if ((start + limit) > plants.Count)
            {
                limit = plants.Count - start;
            }

            List<Plant> rangePlants = (start < 0 || limit < 0) ? plants : plants.GetRange(start, limit);

            return new Paging<Plant>(rangePlants, plants.Count);
        }
