Yes, this is a bit tricky. I have a solution on www.cflex.net <http://www.cflex.net/> and I'll post a link below, but it is not ideal. The issue is making it generic. I have read since about using classFactory and property bag to help with this but have not implemented any of that stuff.
There are two steps. One is to extend ComboBox to allow you to set the selected index by passing in the current value of the main dataProvider item, so that each row displays the correct selected item. This is complicated by the fact that the Combobox's dataProvider can be many formats, and the "data" property can be any property of the item. Of course you need to know the data property in order to be able to loop and compare its value with the main item's data. The second step is to wrap that extended combo in an item renderer. There are two scenarios for setting the dataProvider for the ComboBox list. One using a static dataProvider the is somewhere in a data model. The second possibility is to have a different dataProvider for each item/row of the main dataProvider. This requires that the ComboBox dataProvider data be nested within each main dataProvider item. My solution supports both options, at the cost of requiring a separate itemRender component foe each column.

I am having a couple issues. 1. I would like to populate the comboBox with dynamic data but anytime I put in an value for the dataprovider which calls a bindable variable it tells me it can't find the variable. 2. I tried to set the dataprovider from actionscript when I get the info saying something like pickStat.dataProvider = whatever Problem is that I can't reference the combobox itemeditor from actionscript either. It has the id field specified and named pickStat. The only think I can think is happening is that I can't reference any of the itemEditor stuff until it is actually displayed because it is not there otherwise. Could this be my problem, and if so what do I do to work around this? Code of itemRender and itemEditor is below <mx:itemRenderer> <mx:Component> <mx:Text selectable="false" width="100%" text="{data.statsField}"/> </mx:Component> </mx:itemRenderer> <mx:itemEditor> <mx:Component className="theComboBoxTwo"> <mx:VBox backgroundColor="white"> <mx:Script> <![CDATA[ import mx.collections.ArrayCollection; ]]> </mx:Script> <mx:ComboBox id="pickStat" dataProvider="{new ArrayCollection([{label: 'less than'}, {label: 'is not less than'}, {label: 'less than or equal to'}, {label: 'greater than'}, {label: 'is not greater than'}])}" /> </mx:VBox> </mx:Component> </mx:itemEditor> -- [EMAIL PROTECTED] <mailto:wolf%40wolffebrothers.com> 785-832-9154
