I have a really long list in my advanced data grid. I was
wondering if it is possible to repeat a header row. Does Flex have
this build-in function? Otherwise, I would need to insert a extra
row and make it look like a header.
I don't think Flex has this feature in built, but you can
visit the URL below to see and implementation of a footer for ADG.
You can also try lockedRowCount option. Please find more details at
the URL below.
