Hi Folks,
Warning: I'm quite new at AJAX so I may be missing something obvious.
I just want to defer population of some AccordionPane conent until the pane is actually clicked. I tried using a DynamicPopulateExtender, but I cant seem to hook up the PopulateTriggerControlID to an AccordianPane(no errors, just doesnt seem to fire). If I hook it up to the Accordian instead, it fires, but oddly enough only fires when clicking the content (any content, of any pane) but not clicking any header, which doesnt do me much good anyway.
See anything i'm missing here? Is there an easy way to do this?
Thanks much in advance, code follows.
Greg

Hi Greg,
The problem is caused by not specifying correct id. I changed your code a little bit, and place a span element with a specified id in the header. Then use it as the trigger.
