You want to look at "dataTip" instead of "toolTip". Tracy

The datagrid dataProvider is an ArrayCollection of objects with many properties. Only a few of the properties are shown in the DataGrid. I am currently using this to get a custom tool tip... (mx:script section) private function createCustomTip(title:String, body:String, event:ToolTipEvent):void { var rtt:RequestToolTip = new RequestToolTip(); rtt.title = title rtt.bodyText = body; event.toolTip = rtt; } <mx:DataGrid id="dgRequestList" dataProvider="{requests}" toolTip=" " toolTipCreate="createCustomTip('DELETE','Click this button to delete the report.', event)"> <mx:columns> <mx:DataGridColumn headerText="Id" dataField="iRequestId" width="50" /> <mx:DataGridColumn headerText="Title" dataField="sRequestTitle" width="300"/> </mx:columns> </mx:DataGrid> For example, these objects also have sRequestDescription properties that I would like to show in the tooltip. Thanks in advance, Steve House
