title: display asterisk instead of no value in password field
body: <p>I would like to display asterisk instead of no value in password field. 
  When I am setting up the field as type=text then I can see the plain text. When I set the type as password then I am getting blank field.
  Is there a way to display the value as asterisks? </p>
  
  <pre><code>  &lt;input type="text" id="txtPwd" runat="server" /&gt;           
  </code></pre>
  
  <p>This is the field I have.
  Thanks in advance, Laziale</p>
