Flex 3 DataGrid Footers
I took a few minutes to prove that there is another way to add Footers to DataGrid in Flex 3. The old blog post showed how to add footers to the border. In Flex 3 we added more hooks so you can add other "content areas" to the DataGrid.
I'm short on time so the example isn't fully fleshed out. It could definitely use some optimization as to when and how often it refreshes. It probably needs masking if horizontal scrollbars are on, but at least it should show up in the right place relative to the horizontal scroll bar. There's probably bugs as well, so the usual caveats apply, but it should get you started in the right direction. Also, I did not try this with AdvancedDataGrid. It is actually developed by an entirely different team.
