I recently learned you can do a postback from javascript using
__doPostBack('#<%=LinkButton.UniqueID%>', '')
This method worked well for me, even with updatepanels but now I added another LinkButton and tried to do a postback using the method above. It works but the page refreshes.
I added this LinkButton to an updatepanel and set a trigger. When I normally click on the LinkButton , it doesn't refresh, but when I try the java postback, it does.
*Got it to work if I write ctl00$ContentPlaceHolder1$LinkButton
But this way isnt good for me because I can't change it everytime I move the control
