Hide a report textbox if report is not loaded as a subreport

[Mike]

I have a main report (A) which loads and embeds a 2nd report (B) as a subreport.

Report B can also be loaded on its own, without being contained in report A. 

I would like to hide (or blank out the value) in a Textbox on Report B if it has been loaded on its own. How do I do this?

I resolved this by adding a nullable parameter IsSubreport to the report being used as a subreport (B), then conditionally setting the Textbox value based on that parameter being true.  Then set the parameter to be passed in as True from the subreport ReportSource.Parameters property on the main report (A).  Seems to work fine.
