Count Rows Of a filtered Tablix and show in a different Textbox (Outside Tablix)

Hi All,

I Have to Hide my Filtered Tablix based on rowcount.

At the same time A Seperate informational Textbox should also get hidden. I tried doing as specified by below link :

Steps I followed:

>> In Tablix took another hidden Cell (Let say Textbox_Test) and in expression wrote :countrow("Mytablix")

>>In seperate textboxI am trying to refer that Cell  as ReportItems!Textbox_Test.value

but my text box does not get tablix rowcount at all. Please suggest.

Thanks,

Priya
