Hi. We have an ajax timer in an asp.net master page that triggers a partial page post back. The timer fires every 10 seconds.
I’m getting 502 errors in IE6 and firefox (not IE8) if the timer is firing at the same times as a full postback is happening – ie the user has clicked a button.
Obviously this is because the ajax call is trying to modify a page that no longer exists (as it’s mid postback).
Is there a way to detect when the timer triggers if a postback has been initiated? I know the simple solution is to turn the timer off when a full postback button is clicked before executing the code (I assume this would work), but as this is in a master page it’ll be a big job to go through all the pages that use this master page.
The asp.net application is on an intranet, hence using a timer with a 10 second interval.
IE8 handles the fact that the page has changed happily and never gives the error. I can replicate the behaviour in IE6, firefox and chrome.
