Selected item for mutilple datagrid's

first of all please do not confuse with my question title. It is a single seleteditem on Multiple datagrid ( not multipleselecteditems on a single datagrid).

I have multiple datagrids ( say three ), each datagrid from the lowest depends for its data from the selecteditem from the above datagrid. I have asked questions on selecteditem on datagrid by populating the data from a sqlserver few weeks ago, and i managed to solve this issue with some answers.

WPF SelectedItem binding between two datagrids[^]

is it possible to use the same selecteditem of a datagrid on multiple datagrid's ? for example,in the previous problem it was only 1:1 datagrid, will it be possible to implement the same concept like there are three datagrids,

one - Person

two- PersonDetails

Three- PersonStatus

1. first the Person datagrid loads by default (from the database)

2. Persondetails table data is displayed when a selecteditem is clicked on the Person datagrid(achieved this already)

3. PersonStatus table data should be displayed when the selecteditem is clicked on Persondetails( is this possible, it is like a tree one after the other)

This is how it will look like, I have achieved the selecteditem between the first two datagrid's

My MainViewModel.cs

//Datacontext
        public MainViewModel()
        {
            this.Persons = Person.GetPersons();
        }
     
        // for Person Datagrid
        private ObservableCollection<Person> personValues;
        public ObservableCollection<Person> Persons
        {
            get { return personValues; }
            set { this.SetProperty<ObservableCollection<Person>>(ref this.personValues, value); }
        }

       //for the PersonDetails datagrid
        public ObservableCollection<PersonDetails> Details
        {
            get
            {
                if (this.Selectedperson == null)
                {
                    return null;
                }
                return this.LoadDetails(this.Selectedperson.PersonID);
            }

        }
        // method to load the persondetails data
        private ObservableCollection<PersonDetails> LoadDetails(int personID)
        {
            ObservableCollection<PersonDetails> details = new ObservableCollection<PersonDetails>();
            foreach (PersonDetails detail in PersonDetails.GetDetails().Where(item => item.PersonID == personID))
            {
                details.Add(detail);
            }
            return details;
        }

        // SelectedPerson Property
        private Person selectedPersonValue;
        public Person Selectedperson
        {
            get { return selectedPersonValue; }
            set
            {
                this.SetProperty<Person>(ref this.selectedPersonValue, value);
                this.RaiseNotification("Details");
            }
        }

        //for the PersonStatus datagrid
        public ObservableCollection<PersonStatus> Statuses
        {
            get 
            {
                if (this.SelectedDetail == null)
                {
                    return null;
                }
                return this.LoadStatus(this.SelectedDetail.DetailID);
            }
        }

        // method for loading the Status details
        private ObservableCollection<PersonStatus> LoadStatus(int detailID)
        {
            ObservableCollection<PersonStatus> statuss = new ObservableCollection<PersonStatus>();
            foreach (PersonStatus status in PersonStatus.GetStatus().Where(item => item.DetailID == detailID))
            {
                statuss.Add(status);
            }
            return statuss;
        }

        // SelectedDetail Property
        private PersonStatus selectedDetail;
        public PersonStatus SelectedDetail
        {
            get { return selectedDetail; }
            set
            {
                this.SetProperty<PersonStatus>(ref this.selectedDetail, value);
                this.RaiseNotification("Statuses");
            }
        }

XAML

<Grid>
       <DataGrid Margin="100,12,116,219" ItemsSource="{Binding Persons}" SelectedItem="{Binding Selectedperson, Mode=TwoWay}"  />
       <DataGrid Margin="100,110,116,121" ItemsSource="{Binding Details}" SelectedItem="{Binding SelectedDetail,Mode=TwoWay}" />
       <DataGrid ItemsSource="{Binding Statuses}" Margin="100,210,116,21" />
   </Grid>
