I have created an RDL file that displays dynamic columns based upon a multi-value parameter, hiding based is done by the Visibility property. This is working as expected in the main report viewer screen, returning one page. However when I select page layout I am receiving two additional pages. I believe the addtional pages are coming from the overall report width, but I have to have the report that wide in the designer because of all of the dynamic columns. Is there any way to modify this property through expression at runtime? The width property of the section doesn't have an expression attached to it.
Any ideas would be appreciated. Thanks
