WPF DataGrid with enumerations in Datatable and AutoGeneratedColummns = "True"

Question

I have a problem with my listing, datatable and datagrid. I have the following code:

StateEnum.cs:

public enum StateEnum
    {
        Pass,
        Fail,
        Mandatory,
        Retest
    }

MainWindow.xaml.cs:

private void Button_Click(object sender, RoutedEventArgs e)
{
    ViewModel.MainViewModel vm = VmSingleton.GetVmInstance();
    vm.ModuleRecords = new System.Data.DataTable();

    DataTable dt = new DataTable("TableName");
    dt.Columns.Add("Id",typeof(int));
    dt.Columns.Add("Operation1", typeof(StateEnum));
    dt.Columns.Add("Operation2", typeof(StateEnum));
    dt.Columns.Add("Operation3", typeof(StateEnum));
    dt.Columns.Add("Operation4", typeof(StateEnum));

    vm.ModuleRecords = dt;

    for (int i = 0; i < 5; i++)
    {
        DataRow newDR = dt.NewRow();
        foreach (DataColumn col in dt.Columns)
        {
            int j = 1;
            if (col.ColumnName == "Id")
                newDR[col.ColumnName] = i + j;
            else
                newDR[col.ColumnName] = StateEnum.Pass;
            j++;
        }
        dt.Rows.Add(newDR);
    }
}

MainWindow.xaml

…
<DataGrid Grid.Row="0" ItemsSource="{Binding ModuleRecords}" AutoGenerateColumns="True" />
<Button Grid.Row="1" Content="Ok" Click="Button_Click"/>
…

While the identifier is displayed in cells, enumerations in cells are not displayed directly. When I click on a cell, I can select the correct enumeration. How can i fix this?

Edit:
Sorry for the ambiguous description. In my case, I want to show data data because I don’t know exactly how much data needs to be shown during development. This is why data is chosen. In my example, I can have more or less operations, and I don't know how many there ...

, , . codeexample , :

private void Button_Click(object sender, RoutedEventArgs e)
{
    DataAccess.DataAccessor accessor = new DataAccess.DataAccessor();

    // i dont know how much operations i got at design time
    List<string> operationHeaders = accessor.getOperationHeaders();

    ViewModel.MainViewModel vm = VmSingleton.GetVmInstance();
    vm.ModuleRecords = new System.Data.DataTable();

    DataTable dt = new DataTable("TableName");
    dt.Columns.Add("Id",typeof(int));

    // this is because i have to go through with a for-each 
    // to initialize the header of the table
    foreach (string header in operationHeaders)
    {
        dt.Columns.Add(header, typeof(StateEnum));
    }

    vm.ModuleRecords = dt;

    // fil the datatable with data...
    ...
}

DataTable, POCOs, MVVM. .
Windows, , xaml Window.Resources:

namespace WpfApplication1
{

    public enum StateEnum
    {
        Pass,
        Fail,
        Mandatory,
        Retest
    }

    public class ModuleRecord
    {
        public int Id { get; set; }
        public StateEnum Operation1 { get; set; }
        public StateEnum Operation2 { get; set; }
        public StateEnum Operation3 { get; set; }
        public StateEnum Operation4 { get; set; }
    }


    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            ModuleRecords = new ObservableCollection<ModuleRecord>();
        }

        public ObservableCollection<ModuleRecord> ModuleRecords { get; set; }

        private void Button_Click(object sender, RoutedEventArgs e)
        {

            for (int i = 0; i < 5; i++)
            {
                int j = 1;
                var mRecord = new ModuleRecord();
                mRecord.Id = j;
                mRecord.Operation1 = StateEnum.Pass;
                mRecord.Operation2 = StateEnum.Pass;
                mRecord.Operation3 = StateEnum.Pass;
                mRecord.Operation4 = StateEnum.Pass;
                ModuleRecords.Add(mRecord);

            }
            DataContext = this;
        }
    }
}
