title: DataGridView does not display DataTable
body: <p>I've got the following code which I think ought to be binding a DataTable to a DataGridView, but the DataGridView shows up empty.  The DataTable definately has rows, so I assume that I am binding the DataSource incorrectly some how.  Does anyone see what is wrong with this:</p>
  
  <pre><code>DataBase db = new DataBase(re.OutputDir+"\\Matches.db");
  MatchDBReader reader = new MatchDBReader(db.NewConnection());
  
  BindingSource bindingSource = new BindingSource();
  bindingSource.DataSource = reader.GetDataTable();
  
  this.dataGridView1.DataSource = bindingSource.DataSource;
  </code></pre>
  
  <ul>
  <li>The first line simply gets a handle to the DB that I'm pulling data from.</li>
  <li>The next line is a provides a class for reading from that same db - in particular it exposes the GetDataTable method with returns the data table that I intend to put into the DataGridView.</li>
  <li>The next line is uninteresting...</li>
  <li>The 4th line attempts to grab the DataTable - QuickWatch indicates that this is working...</li>
  <li>The final line is where I assume i've screwed up...my understanding is that this binds the DataTable to the DataGridView GUI, but nothing shows up.  </li>
  </ul>
  
  <p>Any thoughts?</p>
