I don't think labelFunction is intended to update the dataProvider. I don't see how it possibly could, since it can use multiple columns and does not even have to have a dataProvider property associated with it.
If you want this, I heard of a technique that uses a custom item object, with calculated properties like that built in, and when result data is received, one loops over the raw data creating custom objects for each, and assigning them to the dataProvider. This also lets you use labelFunction to change the way the data is displayed, without messing up the underlying data. Currency formatting, for example. Just brainstorming.

For some reason after the field is updated with the total I can't get at that value. The dataProvider that the DataGrid is bound to is a query result that is converted to an ArrayCollection. When the ArrayCollection is initially populated this field is blank. So, I'm guessing that after the labelfunction executes it doesn't update the ArrayCollection to hold the newly calculated value? How can I go about updating the ArrayCollection so I can save it to a database table. I swear I had this working. Thanks, Ben
