I've got a basic radgrid like the following That starts out where some of the items are expanded and some are not
When the radbutton clicks, everything resets to expanded= false
I can easily reopen everything but I don't know how to capture when somebody collapses one of the categories before the radbutton click.
I am not seeing one here clientside api Or is there some serverside event I can force to happen? I don't see a link to serverside api on the demo page.

thanks
