accessing datagrid footer item

I tried accessing the client IDs for a datagrid by looping
through the items in datagrid.items.count after the datagrid.databind()
call.

The problem I am having is that the count does not include the footer
item. I am doing this to write some javascript code to calculate a running
total of the grid values in the footer textboxes, all on the client.

Has anyone experienced this problem? Note - I do not want to do this
in the onItemDataBound event handler as the code for writing the javascript
will then have to be built in pieces as the onItemDataBound events are fired.

I JUST NEED TO ACCESS ALL OF THE DATAGRID'S CONTROLS, INCLUDING THE FOOTER,
IN ONE SHOT.

thanks,
Bob
