I'm trying to figure out, how I can hide those rows in my report where Total Allocation and Total Cost IN BOTH COLUMNS TOGETHER are 0 in SSRS 2008.

For example:

Total Allocation    Total Actual Cost
0                     0                <---- hide
100,00                0                <---- don't hide 
0                     50,0000          <---- don't hide

Here is the screenshot:

Thank you
