Thanks E, I saw that post. I tried using a DataGridItemRenderer -- extending it and putting the core logic in validateNow. This is the default item renderer.... Its not a UIComponent. Is there some speed increase by using the uicomponent?
I *still* get major lag on the scroll bar after 20 or so records. I then remove the item renderer and its better, but its still laggy. I'm on a dual core 2.8 p4 -- I wouldn't expect the datagrid to run this bad. Any other ideas? Best, Austin Alex Harui's blog suggests that extending Canvas in a DataGrid's ItemRenderer is probably not a good idea if you have a lot of visible cells, because of the overhead that comes with using a container (they do a lot behind the scenes that you might not really need). His recommendation is to extend UIComponent directly and programatically lay out your view of the item. e
