Control Template available for Combobox?

Hello,

I need to modify the look of the C1ComboBox.  I tried to edit the template in blend expression but it didn't look like it was possible.  Is there a known structure available so that I can create a template style for the combobox?

Hi, here is the part corresponding to the C1ComboBox in the Ganeric.xaml.
It uses the C1DropDown and the C1TextEditableContentControl, so you might need to customize them too.

Regards
