ASP.NET button doesn’t fire UpdatePanel Async Postback (solution)

By , November 4, 2010 9:17 am

If you’re trying to use a standard ASP.NET button control as a trigger for your AJAX UpdatePanel’s async postback – and it doesn’t fire, try setting button’s UseSubmitBehavior property to False. This will render button as a standard button with __doPostback() call instead of Submit button in HTML markup and will solve your problem.
