You need to implement IDropInListItemRenderer (and the listData property). The listData will give you the column that owns you.

Some of the cells have various icons in them. I am using an itemRenderer to insert an image in the first column. However, I do not know how to use this same itemRenderer/component for the other images, because the component currently has the dataField "hardcoded". I need a way to re-use this itemRenderer/component so that whatever dataField if being used passes itself to the component dynamically. This sounds confusing, but it isn't. Here are the two important snips of code: FROM mainmxml -------------- <mx:DataGrid....> <mx:columns> <mx:DataGridColumn headerText="Image 1" dataField="f3" itemRenderer="IconRenderer"/> <mx:DataGridColumn headerText="Color 2" dataField="f5"/> <mx:DataGridColumn headerText="Properties 3" dataField="f6"/> <!-- I need another DataGridColumn here with dataField="f7" that ALSO uses itemRenderer="IconRenderer" --> </mx:columns> </mx:DataGrid> FROM IconRenderer.mxml ---------------------- <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml <http://www.adobe.com/2006/mxml> " horizontalAlign="center" verticalAlign="middle" width="16" height="16"> <!-- I want to pass an argument to the "data.f3" below, because this component might use f3, f7, or f-something else, too --> <mx:Image source="{'images/icon_' + data.f3 + '.gif'}"/> </mx:VBox> I am sure there is an easy way to make a function here, but I just don't know how. Thanks, Ann
