I've scoured the forums and no one has ever answered this question for other people who have posted it. I have a SSRS 2005 report where the user can choose to expand all groups by selecting yes or no in a parameter called ExpandAllGroups. It works great for the most part - if they chose to expand all groups, then all four groups and my details line all show as expected. However, once they've run the report with everything initially expanded and they decide to collapse group #1 it will actually still retain all the space that the three child groups occupied. So if it took up five pages total and you collapse it, it still has five pages of white space showing between what you just collapsed and the next grouping. My report is massive and I have one group that if you collapse it then you have something like 50 pages of white space until the next group. The only suggestion I've seen is setting up your visibilty property via the group dialog box rather than the visibility properties for the row. I did this to no avail. It doesn't appear to matter if I do it on the row or on the group, it still fails to collapse correctly. Anyone found a solution to this?? There were about a half dozen previous posts with the same issue but no resolution was ever posted. Thanks, Shaunna
