ComboBox doesn't load users

private void LoadUsersToComboBox()
{
    comboBox1.DataSource = null;
    comboBox1.DataSource = peopleRepo.FindAllPeople(); /*Returns IQueryable<People>*/
    comboBox1.DisplayMember = "Name";
    comboBox1.ValueMember = "ID";            
}

private void button2_Click(object sender, EventArgs e)
{            
    CreateNewPerson();            
    LoadUsersToComboBox();
}

private void CreateNewPerson()
{
    if (textBox2.Text != String.Empty)
    {
        Person user = new Person()
        {
            Name = textBox2.Text
        };

        peopleRepo.Add(user);
        peopleRepo.Save();
    }            
}

I'd like the combobox to displ开发者_运维问答ay a list of users, after every save. So, someone creates a new user and it should display in the combobox right after that. This isn't working, no new users are added, only the initial 'load' seems to work.

Complex DataBinding accepts as a data source either an IList or an IListSource.

private void LoadUsersToComboBox()
{
    // comboBox1.DataSource = null; // No need for this

    comboBox1.DataSource = peopleRepo.FindAllPeople().ToList(); /*Returns IQueryable<People>*/
}

Don't reassign the DisplayMember & The ValueMember every refresh, just once,

public Form1()
{
    InitializeComponent();

    comboBox1.DisplayMember = "Name";
    comboBox1.ValueMember = "ID";
    LoadUsersToComboBox()
}

Good luck!
