This is the format how I'm getting my list of users from Stored Procedure.

```
IEnumerable<User> users = new List<User>();

```

Now I'm trying to bind this list to my combo-box like:

```
        private void BindDropdownList(IEnumerable<User> users)
    {
        selectuser_dropdown.Items.Insert(0, "+ New User"); // Want this to be at last position.
        selectuser_dropdown.DataSource = users;
        selectuser_dropdown.DisplayMember = "FullName";
        selectuser_dropdown.ValueMember = "Id";
    }

```

My class is:

```
    public class User
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string Username { get; set; }
    public bool IsAdmin { get; set; }
    public string FullName {
        get
        {
            return LastName + ", " + FirstName;
        }
    }
}

```

But the **New user** doesn't seem to appear in my dropdownlist. What is the issue here and can anybody please suggest a way to do it? Thanks in advance.
