I have a very wide grid (may columns) with grouping enabled. I have tested and been able to reproduce the issue that, when scrolling with the scroll wheel in an IE7, IE8, and FF the browser freezes so it is not browser-specific.
The columns do make use of converters and column templates.
I don't get notification of any exceptions from FF or IE.
It seems to happen more often in IE than in FF though being able to reproduce the error is sporadic. It seems that when I scroll up and down, leave it for a second then scroll to the bottom, then scoll back to the top, pause, then go back at it, I get the browser freeze.
Is it possible to add be ability to disable the scoll wheel support in the grid?
Thanks for your help,
Ryan

Hi Ryan,
Sorry for the late reply! In our current official grid there is no columns virtualization and you may get serious performance problems in case of many columns. We reworked completely the entire grid scrolling and now (after a week) we will upload our Q3 beta2 where the grid will be with container recycling, horizontal columns/cells virtualization, etc.
Can you send us small example where the problem can be reproduced? We will test your scenario with our latest binaries and we will get back to you with more info.
