title: Passing Report Parameters to SubReport in VS 2010 RDLC
body: <p>Passing Report Parameters to SubReport in VS 2010 RDLC</p>
  
  <p>I'm having some troubles defining and passing report parameters to subreports in VS 2010. In VS 2008 in the design view I was able to right click and define the report parameter and have it passed through.</p>
  
  <p>In VS 2010 that prompt is missing. So my question is, how can I pass a value from a parent report to a subreport in VS 2010?</p>
  
  <p>Additionally, this is what is shown in the Report Properties dialog inside of VS 2010:</p>
  
  <p>For the time being I have defined the parameter in the subreport manually in the XML but I'm receiving an error from the main report when I attempt to pass a parameter of any type to the subreport.</p>
  
  <p>The error is :</p>
  
  <pre><code>An error occurred during local report processing.
  
  Value cannot be null. Parameter name: value
  </code></pre>
  
  <p>Where I do not have a parameter named value defined anywhere.</p>
