The instance of relay command is passed to Command property of EventTrigger as shown in  the following code example:

XAML :

<i:Interaction.Triggers>

    <i:EventTrigger EventName="MouseDoubleClick">

        <i:InvokeCommandAction Command="{Binding Path=DoubleClickCommand, Mode=TwoWay}" CommandParameter="{Binding ElementName=grid}" />

    </i:EventTrigger>

    <i:EventTrigger EventName="MouseMove">

        <i:InvokeCommandAction Command="{Binding Path=MouseMoveCommand, Mode=TwoWay}" CommandParameter="{Binding ElementName=grid}" />

    </i:EventTrigger>

</i:Interaction.Triggers>
