AdvancedDataGrid Horizontal Scrolling Performance Fix

A week or so ago some comments were added in the Adobe Flex Bug system regarding the ongoing performance problems with the AdvancedDataGrid's horizontal scrolling. While a proof of concept workaround was posted, the actual issue still remains. 

If you implement the workaround posted you will get smooth horizontal scroll but it is at the expense of an important feature of the grid... Locked Columns. If you have ever used a spreadsheet with many columns you will know that most of the time you need to lock at least the first column so that you don't get lost in the sea of cells. With the workaround that won't work. 

I added a comment on the issue in the bug system, but I urge others to make sure that this temporary workaround is not  a solution to the problem. We all need some better resolution to this issue and it seems that it is likely to stay "Deferred".

Let's not let that happen. Create an account in the Adobe bug system and post your comments at http://bugs.adobe.com/jira/browse/SDK-17880

Votes are even better than comments since it helps with visibility.

Unrelated to this scrolling issue, but possibly you could help me with an advanceddatagrid problem.

I'm using the groupLabelFunction to set the label for the groups in my grid. I'd like to be able to have the label span more than just the first column that its in.

Any idea how to do that?

Thanks Matt... that's a great point. Votes are the way to go.

@lauren - You should be able to do what you want using renderer providers. See http://livedocs.adobe.com/flex/3/html/help.html?content=advdatagrid_10.html

Hi Rob,

To confirm, does the 17880 fix actually fix ADG issue with horizontal scrolling including lockedColumns? seems like the bug is closed but i see no mention of ADG being fixed, just standard DG
