I have a customer that is having issues with exporting to excel. They have a Straight table that has show/hide conditions depending on with selections are picked from a list box. The number of columns is at most 17, so not a huge amount. Row count can be up to 18000 and when trying to export, it just hangs, saying "Exporting" but never actually exports. Even trying less rows, 1500, can take 5 mins. Is this due to the customer using AJAX?
