Hi,
U need to have a combo box renderer something like:
In the object that u are populating the data provider of the
data grid, add 2 fields:
listOfFields & selectedField.
<mx:HBox horizontalScrollPolicy="off"
verticalScrollPolicy="off"
xmlns:mx="
http://www.adobe.com/2006/mxml">
<mx:Script>
<![CDATA[
public var itemSelected: Object;
]]>
</mx:Script>
<mx:ComboBox id="combo"
dataProvider="{data.listOfFields}"
selectedItem="{data.selectedField}"
change="itemSelected=combo.selectedItem;"
updateComplete="itemSelected=combo.selectedItem;">
</mx:ComboBox>
</mx:HBox>
Now, loop through the list of objects that u get from
back-end and keep setting the 2 new properties (listOfFields &
selectedField). For setting the value of selectedField, u need to
loop through listOfFields to match the fieldId.
Hope that helps,
Cheree
