title: How to invoke an event after losing focus from a textbox that was just filled out?
body: <p>I have two text boxes: A and B using <code>Html.textboxfor</code>. TextBox 'A' is enabled and TextBox 'B' is disabled.</p>
  
  <p>When I type values in Textbox 'A' and change focus away from the textbox, TextBox 'B' should be populated with some value.</p>
  
  <p>For example: I am entering the value of TextBox A = "King"; if the focus is lost from the box, the value in the Textbox B should be "Peter", which should be filled automatically.</p>
