SSRS 2008行可见性问题

Question

I am facing following scenario : I have two values A and B and I need to Hide and show it based on ssrs expression. My Conditions :

1. If A = 1 and B = 1 show row
2. If A = 1 and B = 0 Show row
3. If A = 0 and B = 1 Show row
4. If A = 0 and B = 0 Hide Row

(I have tried using AND, OR, XOR, AndAlso, OrElse but it is not working.) (Problem arises because SSRS shows when output is false and hides when output is true)

Answer 1

Select the table detail row (or group row depending your table) and in the Visibility set the hidden expression like below

= ( Fields!A.Value = 0 AND Fields!B.Value = 0)
