InvalidCastException? Are you sure? Why?

Hi,


I think the problem is that you can't cast a ColumnHeader to a ColHeader, because the other away around would always be possible.


How are you creating the items in the Columns collection? I suspect you are probably using the Add overload that implicitly creates the ColumnHeader. Try explicitly creating ColHeaders, and adding those.


Regards,


Nick.
