Ssrs 2008 page break

On an existing ssrs 2008 report, I want to use the page break disabled property. I want to use this property so I can set some iif expressions on when the page breaks occur. The problem is page breaks disabled property is not supported in ssrs 2008. Thus is there another feature I can use in ssrs 2008 instead?

If so, can you tell me what that property is and an example of the code?
If not, can you tell me what version of ssrs reports I would need to use?
