I'd only like to mention that Flexicious [1] offers some powerful Flex datagrids. It's a commercial product, but the fee is very fair including a great support from the developers. The demos looks a bit old school but the product is still awesome.
So if it fits your needs, go for it and support one of the less Flex companies out there ;-) Olaf [1] http://www.flexicious.com/ -- View this message in context: http://apache-flex-users.2333346.n4.nabble.com/Why-are-Spark-Datagrid-headers-sorting-my-data-so-slowly-in-Air-tp13026p13055.html Sent from the Apache Flex Users mailing list archive at Nabble.com.
