Selecting item in ComboBoxAdv not working via C#.

Hi. Here's the thing: I can't figure out how to display a value in ComboBoxAdv via C#. I'm populating the property DataSource with a List from one of my entities (I'm using EF6):

//My list:
var cardTypes = _cardTypeController.GetAllCardTypes().OrderBy(x => x.Type).ToList();

//Setting the DataSource.
cardTypeComboBox.DataSource = cardTypes;

//None of these worked:
cardTypeComboBox.Text = cardTypes[0].Type;
cardTypeComboBox.SelectedIndex = 0;
cardTypeComboBox.SelectedItem = cardTypes[0];

On running time I can select normally the items, but my default values does not show up, I'm getting the control text empty.
The funny thing is that on debugging I can see perfectly these properties and their expected values. What I doing wrong? Why I'm getting the control text empty?

Also I tested the old .Net ComboBox for curiosity. As I expected, it worked like a charm. In the docs it says: "ComboBoxAdv is an advanced combo box control that provides a similar object model as the framework of the ComboBox control". So....what's wrong?
