To invoke a command when an event fires, EventToCommandBehavior might be used; example:

<Entry Text="{Binding Text}">
    <Entry.Behaviors>
        <behaviors:EventToCommandBehavior EventName="Focused"
                                          Command="{Binding FocusedCommand}" />
    </Entry.Behaviors>
</Entry>

See also Event to Command Behavior sample.
