Can't find the ASP.net ListView control
<p>I want to extend the <code>ListView</code> control:</p>

<pre><code>using System;
using System.Data;
using System.Collections;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;
using System.Resources;
using System.ComponentModel.Design;
using System.Globalization;

namespace My.WebControls
{
  /// &lt;summary&gt;
  /// my ListView
  /// &lt;/summary&gt;
  [Designer(typeof(System.Web.UI.Design.WebControls.DataBoundControlDesigner))]
  public class MyListView : ListView
  {
  }
}
</code></pre>

<p>But compiler does not see this control. I include the namespace <code>system.web.ui.webcontrols</code>. Do I have to check anything else? I use the framework 3.5.</p>
