I'm developing an SSRS report that has a Tablix with 5 grouping levels. When the report initially renders, I'd like the report to appear fully rolled up (only top level group visible). As the user clicks the Expand "+" symbols, I'd like each subgroup to appear. I've got the functionality working, but for some reason, there appears to be extra space showing in each group (see red arrows in pic below).
The extra space appears to be a "placeholder" for data that the report knows it will be including once the user clicks the expansion button. But until they do, I'd like to hide that extra spacing that it's currently showing.
