title: How can I utilize Validating/Validated event in Button class?
body: <p>I understand how validated event works with textbox but I don't understand how it's triggered with button on a form.</p>
  
  <p>MSDN doesn't have validated/validating listed in their <a href="http://msdn.microsoft.com/en-us/library/ms609089.aspx" rel="nofollow noreferrer">documentation</a>.</p>
  
  <p>However, both properties are listed as events in properties window.
