How to reference a column's current visibility state
I have a column in a tablix whose visibility is toggled on a textbox. So far so good. I would like the textbox to read "Hide details" when the column is visible, and "Show details" when the column is hidden. The textbox needs an expression something like =Iif(Tablix1.Column1.CurrentlyBVisible = true, "Hide details", "Show details") But I can't find any way to reference the column's current visibility. Any ideas?
