I have a webform in asp.net and It had 2 updatepanels .
on button xyz it posts to server to get some details and Populate a div with repater data
i want to stop the partial postback in updatepanel as
we have e.preventdefault in Normal postback
The second updatepanel is updated via a timer tick event
i tried event.preventdefault
and also event.stopimmediatepropagation but it doesnt seem to work
