Visual studio XAML ExtendedPicker-在ViewModel中调用代码

是否有方法更改此ExtendedPicker，以便在用户更改select数据时在ViewModel中调用MyCode

<controls:ExtendedPicker 
        Style="{StaticResource FormEntry}" 
        x:Name="carTypePicker" 
        Picker.Title="{i18n:Translate SelectCar}" 
        ItemsSource="{Binding carTypes}" 
        DisplayProperty="Name" SelectedItem="{Binding SelectedCarType, Mode=TwoWay}">
</controls:ExtendedPicker>

您不能从SelectedCarType属性的setter调用MyCode吗

private YourType _selectedCarType;
public YourType SelectedCarType
{
    get { return _canFilterByOrderId; }
    set { _selectedCarType = value; MyCode(); }
}
