Question

I have an event trigger that I want to be fired in response to two different routed events. I don’t want to repeat the event response code (in XAML) twice. Can I specify multiple routed events for a single event trigger declaration?

Example of a single event:

<Style.Triggers>     <EventTrigger RoutedEvent='Button.MouseEnter'>         <--XAML MAGIC-->         ...

Sorry… WPF’s implementation of the EventTrigger only allows one routed event.

Typically you would be firing a storyboard from a routed event. I would suggest the following compromise:

<!--Define a storyboard as a resource--> <Storyboard x:Key='MyStoryboard1'>    <!--Many properties and etc...--> </Storyboard>  <Style.Triggers>    <EventTrigger RoutedEvent='Button.MouseEnter'>       <BeginStoryboard Storyboard='{StaticResource MyStoryboard1}'>          <!--Other properties/name if necessary-->       </BeginStoryboard>    </EventTrigger>    <EventTrigger RoutedEvent='Button.MouseDown'>       <BeginStoryboard Storyboard='{StaticResource MyStoryboard1}'>          <!--Other properties/name if necessary-->       </BeginStoryboard>    </EventTrigger> </Style.Triggers> 

The concept is to reduce duplicate code by sharing resources.

Hope this helps!
