Hi,
=iif(Parameters!AX_RenderingCulture.Value = “ar”,FALSE,TRUE)
Note: No needs to validate using controller class or passing the values in DP class for this.
In my case, I needs to change the order ofcolumn of the table in SSRS without reference to arabic from right to left and rest left to right.
So I added visibity based on expression on both the lines as Arabic and rest
