I have some reports with grouping that have all but the group heading hidden by default, using the group heading as a toggle item. Within the details of the group there are some columns that have interactive sorting. When I open one of the groups and click on the sort icon the report refreshes on the screen with the group that I expanded closed again. If I open the group I can see that it has sorted that column properly. Is there anyway to prevent the group(s) from showing up as closed when a sort is done? I see this behavior using the Report Manager or the webform control.

I hate to resurrect an old thread, but this is still a problem with SSRS 2008 and consequently, this post was among the top search results for the query of this problem.-Wes
