After performing a search, I did not find whether someone already posted this feedback, but most likely someone already has. Or maybe it's already in sql 2012 (I am 2008 r2).
it would be useful to have a sql report option that would automatically refresh a report's view immediately after updating a parameter. of course you couldn't do that if the report were based on cascading parameters, for example, but there are cases when it would be nice to have a report automatically refresh or re-render as soon as a parameter is updated. I know a default value will do this when you first open a report, but I am talking about continued use of the same report by simply changing a value in the parameter prompt to some other value. my end-users complain about having to constantly reach over and click the [View Report] button during their data analysis; I can see their point.
