I have an SPD data view webpart that I want to group on a certain field. When I
select "collapse group by default" the webpart opens with the groups expanded.
The plus minus icon next to the field value is a plus. So I click the plus, and
it turns to a minus but nothing happens since the groups are already expanded.
Then clicking the minus icon causes the group to collapse. Is there some parent
control that I need to set? What am I missing?
