         try {

                 if (arrayCollection.length > 0) {

                     return ko.utils.arrayFirst(arrayCollection, function (item) {

                         return (item.labelName.toLowerCase().indexOf(labelName.toLowerCase()) > -1);

                     });

                 };

          }

          catch (ex) {

               //TODO: as per need.

          }
