title: How do you add a listbox as an input parameter UI element in SSRS 2008?
body: <p>I have to add a listbox/dropdownlist to a report in a Visual Studio Business Intelligence project, allowing users to filter a DataSet by the Id of the entity chosen in the listbox. I heard this was possible, but there is no option to add a listbox in the Toolbox in Visual Studio, and looking at the <a href="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition/ReportDefinition.xsd" rel="nofollow noreferrer">Report Definition</a> on microsoft.com, there's nothing there about a listbox.</p>
  
  <p>What am I doing wrong here?</p>
