          If you use XMLList type for DataGrid dataProvider you should manualy set myGrid.dataProvider = dg after you have change dg. Or you can use XMLListCollection instead.

          And i cann't understand why you use xml for data storing.
          It seems to be easier to use ArrayCollectionList for storing your LogReaders and use filters there.

            Without looking at your code, here are few pointers:

            1) Take a look at filterFunction property of your ArrayCollection
            2) Remember to call ArrayCollection.refresh() everytime you set or clear the filterFunction property

            Here is working code, basically on every keystroke of your search input box, or whatever event you like to choose, you cann filterList function that sets the filterFunction property of array collection, that implements ICollectionView, to the local filter function that provides the logic for including the rows in the filtered view:

            private function filterList(event:Event) : void {
            var view:ICollectionView = this.dataGrid.dataProvider as ICollectionView;

            if (view.filterFunction == null) {
            this.totalRows = view.length;

            if (!view) return;

            if (this.searchTextInput.text.length == 0) {
            view.filterFunction = null;

            view.filterFunction = filter;
            private function filter(item:Object) : Boolean {
            var s:String = ObjectUtil.toString(item, null, ['mx_internal_uid', 'Pretty Print', '#']);
            // trace(s);
            return s.indexOf(this.searchTextInput.text) >= 0;

              hye...can you give me more detail on this??i have tried to implement your code and i get these errors:

              -Access of undefined property ObjectUtil.
              -Access of possibly undefined property totalRows through a reference with static type Project.
              -Access of possibly undefined property dataGrid through a reference with static type Project.

              hope you can help..i'm new to this...

              thanks in advance

                You should remove the implementation of the filter(item:Object) function and instead give your own implementation that returns false if current row, passed in as item parameter, should be filtered.
