title: ObjectDataSource -> Method taking two params one being Connection String
body: <p>I am updating an old website to a more modern look.  They want the ability to <code>CRUD</code> their datatables so users can easily edit/update/delete things without going to special pages.</p>
  
  <p>To do this I'm setting up an ObjectDataSource to their old methods.</p>
  
  <p>Their methods take a param of Connection String </p>
  
  <pre><code>GetCustStaff(string cstGID, string ConnString);
  </code></pre>
  
  <p>How do I tell the ObjectDataSource that the ConnString value comes from the web.config?</p>
  
  <pre><code>ConfigurationManager.AppSettings.Get("Connection").ToString()
  </code></pre>
  
  <p>The only options it gives me to fill the Param are <code>(None, Cookie, Control, Form, Profile, QueryString, Session, RouteData).</code>  </p>
  
  <p>Anyone have any idea how I can circumvent this?</p>
