Hello,
Using: VS 2013 and WinForm version of ReportViewer 2012, report is LocalReport.
I have designed a report using a single Tablix with one group and a ToggleItem which looks and functions exactly the way I want it to, with one exception - if I change it to initially be collapsed (by setting the appropriate Row Groups' Hidden property to True), all of those row groups are invisible when I expand using the ToggleItem.
Here is the report before changing to being initially collapsed:
Here is the report when started in Collapsed mode and after expanding one row:
I have also tried driving the initial collapsed behavior through a parameter, but the results are exactly the same - expanding using the ToggleItem makes space for the data that should be shown, but ALL rows are invisible.
I have spent two days trying to resolve this, or to even find someone else reporting the same behavior, but I have not been able to resolve it. I hope you can offer some input or provide a workaround, since nothing I've tried has worked.
Thanks,
Matt
