    In the Page_Load you should install a handler for the btndelete.Clicked event. My VB is a bit rusty so I abstain from offering the exact code. ASP.NET will ensure that this event is fired if the button was indeed clicked.

    That said, why do you need to create dynamic buttons? Look into defining the button in the markup and just manipulate the Visible property instead.
