          You can try using enableAutoUpdate or refresh properties in ICollectionView if grid is to be refreshed after data is chnaged. If only one item is chnaged or updated in sourcedata the itemUpdated method is to be called below.


          ICollectionView(myGrid.dataProvider).itemUpdated( event.item, myGrid.columns[event.columnIndex].dataField );













          ICollectionView(myGrid.dataProvider).enableAutoUpdate = true;


          Let me know if this is helpful.

            actually when u want to remove the data from the data grid u have to vacant the data from ur dataprovider.


            in ur case if u once create the objet of arraycollection no need to crea this object again.

            there is a property removeAll() properties in array collection

            just use it,

            see following i give a example



            <?xml version="1.0" encoding="utf-8"?>




            xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">






            import mx.collections.ArrayCollection;




            private var gridData:ArrayCollection = new ArrayCollection([{col1:'abc', col2:'def', col3:'xyz'},

            {col1:123, col2:456, col3:789}]);



            private function removeData():void









            <mx:DataGrid dataProvider="{gridData}" x="70.5" y="84">






            <mx:DataGridColumn headerText="Column 1" dataField="col1"/>



            <mx:DataGridColumn headerText="Column 2" dataField="col2"/>



            <mx:DataGridColumn headerText="Column 3" dataField="col3"/>







            <mx:Button x="160" y="274" label="clearedata" click="removeData()"/>
