イベントに添付された動作を使用できますMouseDown
。
次の質問を参照してください。WPF/MVVM-ViewModelでTreeViewItemsのダブルクリックを処理する方法は?
あなたの場合、それはこのようになります
<ItemsControl ItemsSource="{Binding ...}">
<ItemsControl.ItemContainerStyle>
<Style TargetType="ContentPresenter">
<Setter Property="commandBehaviors:MouseDown.Command"
Value="{Binding YourItemClickCommand}"/>
<Setter Property="commandBehaviors:MouseDown.CommandParameter"
Value="{Binding}"/>
</Style>
</ItemsControl.ItemContainerStyle>
<!-- ... -->
</ItemsControl>
