Attached actions not working with left mouse button

Feb 7, 2011 at 7:42 PM

I'm trying to do what I think is a simple button with discrete events for MouseDown and MouseUp:


<Button x:Name="PowerButton" Content="Power" Height="23"  Width="75" 
  cal:Message.Attach="[Event MouseDown] = [Action PowerDown]; [Event MouseUp] = [Action PowerUp]" />
But PowerDown/PowerUp only invokes when using the right or middle mouse buttons. Is something else preventing CM from seeing the left mouse button events?

It all has to do with the events. Under the covers this uses an System.Windows.Interactivity.EventTrigger. It wouldn't have anything to do with CM I don't think.

Thanks. Once I stopped worrying about the CM part of the equation I realized I need to use Preview* events on a button since it stops bubbling for individual left mouse events. Works great now.
