title: Incorrect date format conversion with TextBox
body: <p>I want <code>MM/dd/yyyy</code> date format but TextBox gives this date format <code>yyyy-MM-dd</code>. While TextMode is Date.</p>
  
  <pre><code>&lt;asp:TextBox ID="txtChkEventDate" TextMode="Date" runat="server"&gt;&lt;/asp:TextBox&gt;
  </code></pre>
  
  <p>I've used this code to convert the format:</p>
  
  <pre><code>string[] formats = { "MM/dd/yyyy" };
  var dateTime = DateTime.ParseExact(txtChkEventDate.Text, formats, 
                      new CultureInfo("en-US"), DateTimeStyles.None);
  </code></pre>
  
  <p>But it show error:</p>
  
  <blockquote>
    <p>String was not recognized as a valid DateTime.</p>
  </blockquote>
  
  <p>How I can convert <code>yyyy-MM-dd</code> into <code>MM/dd/yyyy</code> date format?</p>
