You create the dynamic button in the click event handler of btnMain during the postback caused by btnMain click. After that you see the new button in the browser page, click it and expect its click event handler (btnNew_Click) to fire. Pressing the new dynamic button causes a new postback that is processed by a new instance of the page created on the server by ASP.NET. This new page does not have the dynamic button - there is nothing there connected to btnNew_Click. You have to write code that persists the fact that the dynamic button has been created and recreates this button every time the page is instantiated. So that this button has a chance to feel and respond to its client-side click.
