Form executed by F5, no data listed

Question

Hi

I am new to Visual Studio Express.

Created a Windows form  (C#).

Added a listbox and in properties databinding, advanced. 
 
I bindend to table: CostumerBindinSource - CompanyName

Then pressed F5 and see only an empty box.
Using 2012 version. 
I expected see all data of table displayed in form listbox.


Please clarify
