title: Cannot choose new data source from ReportViewer control
body: <p>I'm following an ASP.NET tutorial about <em>Reporting Services</em>. I am at a point where I add a <code>ReportViewer</code> control to my <code>aspx</code> page. From there I have to select the report that I want to use and add a new <code>Datasource</code>. But adding the datasource is where I'm having trouble.</p>
  
  <p>The tutorial says I have to choose: <code>Choose Data Sources</code> from the <code>ReportViewer</code> and then select: 'New data source`. But I don't seem to have that option.</p>
  
  <p>This is from the tutorial:</p>
