Any method to hide the worksheet using report tags?
Currently there isn't (only to <#delete sheet>, but not to hide ). But I think it could be added easily, so we'll see to add it to the next release.
As a workaround for now, you could use the TFlexCelReport.AfterGenerateSheet Event | FlexCel Studio for VCL and FireMonkey documentation event, and hide the sheet if needed. The event will fire once for every sheet.
