Whenever a button is clicked it will be posted back to the server. You can test this by placing a break point in your page load event as well as your button click event and see the flow of the application.

Thank you for your reply.
I understand the flow. I have two buttons, button1 initiates a postback and adds a table control and button2 to the page . When Button2 intiates a postback. the supporting code for it will take the contents of the table added by button1 and extract the changed fields. I need a method to determine which button initiated the postback. so that if button2 initiated it I can recreate the table control to be manipulated by the button2 codebehind.
Does this make more sense?
