title: Grid not displaying its rows
body: <p>I'm using <code>Infragistics.Win.UltraWinGrid.UltraGrid</code> version <code>Infragistics4.Win.UltraWinGrid.v13.1</code>
  and I have some problem getting this code running properly.</p>
  
  <pre><code>// creating the dataSource object which is a wrapper for a System.Data.DataTable
  dataSource.FillTheValues();
  Infragistics.Win.UltraWinGrid.UltraGrid grid = new Infragistics.Win.UltraWinGrid.UltraGrid();
  
  grid.DataSource = dataSource.Table; //dataSource.Table is a System.Data.DataTable
  grid.DataBind();
  grid.PerformLayout();
  </code></pre>
  
  <p>At this point something very strange happens (checked in debug mode):</p>
  
  <ul>
  <li><code>dataSource.Table.Rows.Count</code> is 1203</li>
  <li><code>grid.Rows.Count</code> is 1203</li>
  </ul>
  
  <p>but in the actual grid in my form nothing is displayed and the grid appears totally empty.</p>
  
  <p>The Columns in the grid perfectly macth the one in the <code>dataSource.Table</code>, so the binding is fine.</p>
  
  <p>Additionally, I've tried to invoke <code>grid.Update</code>, <code>grid.Refresh</code>, <code>grid.Invalidate</code> but no result.</p>
  
  <p>Do you have any idea ?</p>
