I’m using Blazor Web App and have a component that uses EditForm and ValidationSummary. All works well, except I want to sort the error messages by the order specified in my model. Here’s my simpified-for-example model:

public class ContactModel
{
  [Display(Order = 1)]
  public int ContactID { get; set; }
  [Required]
  [Display(Order = 2)]
  public string FirstName { get; set; }
  [Display(Order = 3)]
  public string MiddleName { get; set; }
  [Required]
  [Display(Order = 4)]
  public string LastName { get; set; }
}

I’m adding a custom validation (example only) that if a middle name is entered, it must be at least 5 characters.

if (!String.IsNullOrEmpty(_model.MiddleName) && _model.MiddleName.Length < 5)
{
    messageStore?.Add(() => _model.MiddleName, "Middle name must be at leaset 5 characters.");
}
_editContext.NotifyValidationStateChanged();

If I leave the first name blank and only enter two characters in the middle name, I get the two validation errors in the ValidationSummary… BUT… through some other testing I have found that the custom errors are displayed before that annotated errors. This makes the order

'Middle Name' must be at least 5 characters
'First Name' is required

I want to display the messages in the order defined in the model’s

[Display(Order = XX)]

attributes. How can I do this?

Thank you
