[flexcoders] Tooltip in Advanced datagrid

[senthilkumarirtt]

hi all,i need to create tooltip for Advanced datagrid column by make 
CustomDataGridItemRenderer extends Label Action class.

i use this code to implement tooltip,but its not working..


package
{
        import mx.controls.Label;
        
        public class CustomDataGridItemRenderer extends Label
        {
                
                        
         new Label().toolTip="{data.acn}";
        }
}


here "acn" is datafield for that column.
