It sounds as if you want to know which user control the user clicked
in. You can handle a specific event, like a button click event, inside
the user control logic.
For a good example see: Handling User Control Events
Note: The load function in the parent web form will always fire and
will have IsPostBack set to true. I'm not sure why you had to remove
FORM elements from the user controls, they should not have any.
