You can attach the button's onclick event to the function. Should be something like this ( i would put this in the OnPageLoad function )

XMLUpdateButton .OnClick += new EventHandler(up dateclick);

The code didnt fire with the on click? or the write to xml didnt work? If the code didnt fire, make sure the button in question does a postback.
