This property does work as described in documentation.
The difference is in CF's DataGrid (and some classes in
System.ComponentModel) which basically does not pay attention to this
property.
Anyway, I understand it might be tough to move from desktop to CF, it
seems so limited, even crippled, at first.
I hope it'll pass after a while, just like in this case:
http://www.mperfect.net/cfBcl/ J
Please see sample below on how to hide column in the DataGrid (works on
both CF and desktop), does not matter which data source is used.
It also "refereeing to the table by index number" just fine.
If you meant something different, please explain and/or provide code
sample, most likely there's another way to do it.
Best regards,
Ilya

That's quite the duplicitous response. As you are well aware, it does not
work in the same manner as it works on the full framework. With the full
framework, you can refer to the table by index number, but not in CF. I
guess MS would call that working "properly", as Bill Clinton wants the
definition of "the"...
As I said, MS crippled CF by removing the
