By "it returns null" I assume that you mean you get a Null Reference exception - ToString cannot return null.

The question is, what does the rest of your code look like?

You say you are creating this at run time - did you put any values in? Did you set a value for the combobox or leave it as a blank drop down?
Where did you put that code? In the SelectionChanged event? If so, then you will get an event (and a null reference) when the DataGridView is first created.
