I have my report page size setting to 8.5” x 11” with .5” left and right margins. In the design mode, my tablix is wider than the 7.5” allowed page width due to the presence of some conditionally displayed columns. This is okay though as the total width of the displayed columns will never be greater than 7.5” when the report is run. I have also set the report parameter ConsumeContainerWhiteSpace to true. The report displays correctly on the screen and contains the appropriate number of pages when exported as a pdf document. The problem I have is when I want to use this report as a subreport contained in a List report. The subreport control is just a place holder so I can design the List report and everything fits nicely within the 7.5” width limitation. However, when the List report is rendered, it appears that the width of the List report expands to match the design time width of the subreport (not the rendered width). This causes extra pages to be generated when the List report is exported as a pdf document. I have not been able to find any properties that would prevent the List report container from expanding or any properties that might cause the container to shrink after rendering. Any help will be greatly appreciated.
