AutoGenerateField not working in wpf datagrid

Question

I am binding my datagrid to an observableCollection of Class CustomerDetails, I want to hide one of the property from being displayed on the UI as column, for which i am using AutoGenerateField to false, still this column is getting displayed in UI, what am i missing ?

my xaml file is like below :

<DataGrid AutoGenerateColumns="True" ItemsSource="{Binding DataGridItems}" 
                      Margin="1" IsReadOnly="True" SelectedIndex="{Binding SelectedItem }"

ViewModel.cs:

 public ObservableCollection<CustomerDetails> DataGridItems => _model.CustomerDetailsList;

Model.cs

 public ObservableCollection<CustomerDetails> CustomerDetailsList { get; set; }


public MyModel()
        {            
            CustomerDetailsList = new ObservableCollection<CustomerDetails>();    // assume that my list of customers is initialized here      
        }  


 public class CustomerDetails 
    {

        #region Constructor

        public CustomerDetails()
        {

        }

        #endregion

        #region Public Members        

        public string CustomerName
        {
           get; set;
        }

        public string CustomerID
        {
            get;set;
        }

        public string ProductCode
        {
            get;set;
        }
// want to hide this from getting shown in Datagrid
        [Display(AutoGenerateField = false)]
        public string ProductInternalId { get; set; }

Likely you are running into the same underlying problem as:

• Display "Display name" instead of field name in WPF DataGrid

You should handle the AutoGeneratingColumn event to cancel the generation of the column (you can base your logic on the field attributes to still make use of [Display(AutoGenerateField=false)]):

• https://learn.microsoft.com/en-us/windows/communitytoolkit/controls/datagrid_guidance/customize_autogenerated_columns

Alternatively you could turn off AutoGenerateColumns and add the ones you want to the datagrid columns template manually.
