Tiemr in masterpage web site C#
 

Hello,
I have website and wish to put timer in the master page, cause i want to have flash banners changing every tick of the timer.
I have added a timer to my master page, and in timer_elapsed bind my bannerrotator whith the flash - actually the flash is not displayed. when i bind the bannerrotator not by timer (in the page load of masterpage) - the flash is displayed.
By debug i can see the timer works and get in the timer_elapsed event.
Anybody knows the reason and how to solve it?

thanks,
gila
