Item doesn't show text on selection

[HKSHK]

Hi guys,

I have a problem with the combo box I'm writing on.
What I want is custom items, which are fine so far, but when I select
one the combo box shows the project name
("WindowsApplication1+ListItems")... What's wrong? The source code is below.

Thanks in advance!

Best regards,

Probably beacuse you're shadowing the ToString method in the ListItems
class. Try overriding it instead
