Hi Ben,
Thanks for your advice - as is so often the case, we have no answer to the question at hand (why does a dataChange event fire when the datagrid is scrolled?), but I was able to work around the problem by completely changing my mindset regarding the data model. and probably made my app significantly better in the process. So, thanks for triggering that thought process! -tom _____ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of ben.clinkinbeard Sent: Monday, December 18, 2006 5:16 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: How do I reset itemRenderer inside DataGrid when dataProvider is updated? Hey Tom, This thread is pretty old and I don't have time to read through it all again to gain context, but I can offer a quick recap of what (I think) I am doing differently these days. It seems to make things a lot easier if you use ArrayCollections as your dataProvider rather than XMLListCollection, especially if your AC is full of bindable class instances. Check out Darron Schall's ObjectTranslator (darronschall.com) to ease the process of creating typed objects from the generic ones returned by a WS. If this is completely not helpful to your situation due to my lack of reading the thread I apologize. I am walking out the door so here is hoping this is useful :) Ben --- In [EMAIL PROTECTED] <mailto:flexcoders%40yahoogroups.com> ups.com, "Tom Lee" <[EMAIL PROTECTED]> wrote: > > Ben, > > Did you ever find a satisfactory answer to this?
