DAX Count product filter

[Anonymous]

Hello, I have a report matrix of product and category, my problem is apply a DAX measure that count row for every catgory with numb of product. I need a DAX cause the report should work with different filter applied 

Here a pic of what I get, and in orange how should be do it (maybe with just the count in the global rows)

thanks to everyone try to answer!

Perhaps something along the lines of countrows(values(productdim[product]))

Kind regards, Steve.
