I have no control over the dataProvider at all. Performance is not an issue,
because the data extraction only happens once, and it can be time-sliced it so
the webapp does not appear to freeze. Passing through multiple event handlers,
including EnterFrame would be perfectly acceptable.

Because this is an library for exporting to other formats I only need to
instantiate one renderer at a time. Memory requirements should therefore be
modest.
I have implemented a mechanism to export the display lists of non-text item
renderers. The tricky part is learning how to instantiate
My recommendation is to borrow code from DataGridBase

I will answer, but you probably won't like the answer.
This is simply not possible. In order to optimize performance, DataGrid and
the other list components only create(render) the visible elements. If a
row is not visible, it does not exist. You can't look sideways into your tv

I need to post the displayed data to a server, complete with formatting. The
dataProvider does not help much; I'd have to replicate the work that the
datagrid does in determining the properties displayed by each column, and
duplicate the job of the item renderers in order to extract the
If you don't have too many items in the dataProvider, you could create a second
DataGrid, with the same DataProvider and itemRenderers, that does not have a
height set and is not visible. The second DataGrid would render all of the
items in the dataProvider, because the height isn't set. Then

Alex,
Your code is very interesting, and quite instructive. Thank you.
You said that your code handles labelFunction and dataField; however the asdoc
for the itemToLabel() method reads:
public function itemToLabel(data:Object):String
Returns the string the renderer would display for the
