I am using SSRS 2005 with MSBI Studio 2005. This seems like the simplest problem but for some reason i cant get it to work. I am trying to toggle the details grouping to only become visable when a report item is toggled. However when i go to the properties menu and click on details grouping. I go to the visibility tab and the check box to have visibility be toggled by another item is greyed out. I cant check it. It makes no sense to me. Can anyone help? I am missing something obvious
