Binding a generic List<string> to a ComboBox

I have a ComboBox and I want to bind a generic List to it. Can anyone see why the code below won't work? The binding source has data in it, but it won't fill the ComboBox data source.

FillCbxProject(DownloadData Down)
{
  BindingSource bindingSource = new BindingSource();
  bindingSource.DataSource = Down.ProjectList;
  cbxProjectd.DataSource = bindingSource;
}

On a side note: Is it bad to pass around an instance of a class?

Thanks!

If anyone finds this necro thread, make sure your list does not contain null items. Otherwise binding will fail silently!

//This will not work!
comboBox1.DataSource = new List<string> { "test1", null, "test2" };

//This is legit!
comboBox1.DataSource = new List<string> { "test1", "", "test2" };
