Hi, Done and checked in, so you should now see significant improvement in performance with bot the mx:ADG and mx:DG over previous version of the SDK. Your millage will vary but it's more noticeable with the ADG, sorting, horizontal scrolling and for larger data grids.
Also fixed a bug with the mx:DataGrid and caching of headers, the code assumed that columns wasn't a copy and modified it (which mean it was never cached). Thanks, Justin
