Well,

I couldn't get any help on this anywhere on web., What I found on the web is, we have to set language property design time only. We can not change it while running the report.

But, I found an intermediate solution for time being. I created two separate columns in order to hold GBP and EUR currencies and based on parameters I am setting Visible property to True/False and solved my issue right away.

Thanks for taking your time to read anyway.

Keep supporting.

Thx
