I'm trying to databind a combobox in WPF for the first time and I can't get it to happen.

The image below shows my code, can you please tell me what I am missing? I only want graphic stuff in the xaml.

```
private void Window_Loaded(object sender, RoutedEventArgs e)
{
    Patient p = new Patient();
    this.cbPatient.DataContext = p.SelfListAll();
    this.cbPatient.DisplayMemberPath = "Name";
    this.cbPatient.SelectedValuePath = "PatientIDInternal";
}

```
