Ajax Accordion - Multiple controls with the same ID '_content' were found

Question

Hi

I'm dynamically adding accordion panes to an Accordion Control. When I add a single pane, no problem but trying to add 2nd pane I get the exception: *Multiple controls with the same ID '_content' were found*

I've tried assigning unique Ids to the panes as follows but not joy. Can anyone please help?

Thanks

Rob.

Fixed it! Don't know why but assigning the PaneId directly after declaration (on the following line) is critical.
