Reporting Services 2010 RDLC: Passing Querystring Parameters from an RDLC

I'm trying to build a simple RDLC report that shows some data, and has a 'selec开发者_StackOverflowt' link that sends the browser off to a certain url with some data in the querystring (a key).

In the vs2010 report designer, I can double-click on the column, then select action, and there are a bunch of thigns that seem like they might work. But none of them do.

Under 'enable as a hyperlink' I can pick 'go to url' but there aren't any parameter options to pass.

I also tried 'go to report' on the off chance that I could trick it into doing what I want. Here there are parameter options, but it knows that my url is not a report and the "select" link renders as text (not clickable).

Any ideas? I'm pretty sure this used to work in vs2008, and it seems like something that must be doable. But I've been pulling out my hair for several hours on this one.

Did you use the expression builder? I am writing a blog post on this.
