title: C# - Report rdlc add parameter dropdown box
body: <p>I´m new to Visual Studio Reports. I added a parameter to my report with a default value and a query to define the available values.
  The parameter is working, my report is generated with the default values.</p>
  
  <p>But how can I add a dropdown box to select the value from my parameter?</p>
  
  <p>I think there must be a ootb dropdown box to select the value or not?</p>
