Question

I want to Hide my Header Text boxes based on the matrix. How can I set the expression in visibility setting?

Answer 1

Goto the prepertied of the text box and then goto Visibility. Select "Show or hide based on expression" and click on the [fx] button.

Assuming you wantt o show or hide depending if the Matrix is empty or not

Then enter the below: =iif(CountRows("NameOfTheDataseOfTheMatrix") < 1,True, False)
