i dont think there is much difficulty in doing that..As am a begginner i dont know whether am answering according to your question. from my understanding point of view i think that you just need to handle your problem by having different button click function for each button and returning the control  to the main ui using the return keyword from the btnclick function.By returning the control to the main ui after performing the function on the button click the page will continue its executiion.. can u please explain ur scenario of ur problem little to me.
