dpends on how you are enabling the control. if you are using a PostbackUrl,
this is done in javascript by setting the button's onclick event to
WebForm_DoPostBackWithOptions. one of the args is the postback url. this
function updates the action, does a form submit and cancels the buttons event.
view source to see what javascript is on the button's onclick (maybe you
defined an action that prevents the proper behavior).
