Employee.cs

public class Employee {
    public int ID { get; set; }
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    public DateTime? BirthDate { get; set; }
    public DateTime? HireDate { get; set; }
    public string? Email { get; set; }
}

To change the input mask at runtime, use the IMaskedInputSettings.Mask property instead.
