Run AJAX Animation on First PostBack Only

Hi,

I need to run AJAX animation on first PostBack of site.

This is not the initial load of page but the first PostBack. This means that standard ‘OnLoad’ event would not work. Also, it must happen on the ‘first’ PostBack only – none of following PostBacks.

Can anybody help please?

I tried placing panel to be animated within an UpdatePanel to see if I could isolate PostBack this way. However, I found that placing a Panel that has AnimationExtender associated with it within an UpdatePanel just caused an exception.

Thank you.
