Firing the Command event for all items in a repeater

[Barry]

Hi,
I have a Repeater in which the first field has a linkbutton. I also have
a button outside the repeater. When a user clicks the linkbutton, I want
it to fire every linkbutton's click event within the repeater (so it
will expand the next level of a drill-down). I'm stuck on how to fire
this event. If I call the ItemCommand event handler, where do I get the
arguments?

TIA,
Barry
