推荐答案

您可以使用 System.Windows.Interactivity或MvvmLight中的EventTrigger

<DataGrid x:Name="myProtokollList">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="MouseDoubleClick">
            <i:InvokeCommandAction  Command="{Binding Path=OpenCommand}" CommandParameter="{Binding ElementName=myProtokollList, Path=SelectedItem.OriginalSatzX}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
