title: WPF Trigger command
body: <p>I know in Silverlight there is a concept  of behaviours.</p>
  
  <p>In WPF we have Triggers,</p>
  
  <p>What I am trying to achieve is that when a user has his mouse over a button, I want a command to be fired.</p>
  
  <p>I have a RepeatButton that has its Command Property set, but I want that command (or preferable another command to fire) when the mouse is over that button.Is this possible in WPF.</p>
  
  <p>The Button is in a Control Template.</p>
  
  <p>Thanks</p>
