They're display only. Here's my renderer:

I also tried using an embedded image -- seemed like the performance
was pretty similar between the two methods.
Thanks!

As an aside: I'm starting to think that optimizing the horizontal
scrolling is simply not going to be possible.
What do you think of futzing with the scrollbar so I can make it
render on the left side instead of the right side (for vertical
scrolling) ? Would that be terribly difficult? If I

Hey Alex,
As mentioned -- I did try that (using the code from your blog), even
using a labelFunction instead of dynamically detecting the on/off: it
was still about the same speed. The performance hit is somewhere else
deep inside DataGrid. I've spent many hours researching performance

Hey Alex,
I know, it's hard to believe -- but I guess you'll just have to trust
me on this one ;) I've made this same renderer about 10 times and
spent a good 40-50 hours trying to improve the performance -- even
going so far as removing all logic from it at times. It's not the
renderer itself

Ah sorry, I missed that question. There's 30 visible columns right now
(70-ish total), with about 20 visible rows (depends on your viewport
height).
Does anyone know what might make horizontal scrolling of datagrids
really, really slow? Even with default headerRenderers, scrolling
horizontally takes about 1-2 seconds per scroll, while vertical
scrolling is nearly instantaneous. My cells are almost square -- so
it seems like it should be

I'm using a custom itemRenderer that displays a checkmark (or not)
right now (I spent a long time optimizing it -- the itemRenderer is
good to go). Right now about 600 itemRenderers are visible at once
(though more than half of them are technically empty).
I guess I'm mostly stumped at how
