I'm trying to save the user's GroupByRow's expanded state into a database without a post back.  I need a way to be able to show a description field for the group's text and have the value be a the group's ID. I was going to use the AfterRowCollapsedHandler and AfterRowExpandedHandler javascript events to send the data to the database but I haven't found a way to have the rowId parameter of these events be the group's ID from the database - it only shows the HTML element ID.  Can I get data from a hidden row during the AfterRowExpandedHandler event?
