generic page to handle many usercontrols events passing to iframe

[groovq]

i have page1 which contains a user control and an iframe.

the user control has various text boxes and a button to submit.

i would like to have page1 handle the user control click event, load
another page into the iframe, pass the usercontrols values to it and
databind.

page1 would actually load a series of different controls dynamiclly.
the user controls could have any number of values that need to be
passed to their corresponding iFrame target page.

any ideas?
