You have to make sure your custom ArrayCollection throw the "change" event I believe the DG looks for this. (could be another event name, not sure, you will need to check the docs) Dimitrios Gianninas RIA Developer and Team Lead Optimal Payments Inc.

I have a DataGrid with a dataProvider that extends ArrayCollection. The only overridden behavior is that if dataProvider is supposed to return null, it throws an ItemPendingError instead. Here's psuedo-code for what's going on: dataGrid.dataProvider = new ArrayCollectionExt(); // works, dataGrid is blank dataGrid.dataProvider.source = new Array(newLength); // works, DataGrid gains scrollbar and has no values dataGrid.dataProvider.setItemAt(objectSource, 0); // dataGrid is not updated. Am I doing something fundamentally wrong or do I need to track down a bug in my code?
