Hi,
I have master page and there are child pages that is using ajaxmanager. Now we had requirement to add one button on master page and if user click on this button, whole page don't need to be refresh. I was trying to add ajaxmanager on Masterpage but there was an error saying only one instance of ajaxmanager can be used. Is there any other way?
Thank you.
Best regards,
