I have a line and a table in my report that I want to hide if my dataset has no rows in it.
I tried using the expression =CountRows("MyDataSet") > 0
in the initial visibility but this always evaluates to false, even when there are rows in the dataset.
I suspect initial visibility is run before the data is loaded into the dataset.
How can I set the visibility of my table and other elements (a line), based on if the dataset has any rows or not?
