Dumb Question

[Andy Williams]

Is it possible to populate a datagrid on a windows form using a datareader?
I do it all the time in asp.net, but I'm new to windows forms and I can't
get it to work. I get:

An unhandled exception of type 'System.InvalidCastException' occurred in
system.data.dll
Additional information: Object must implement IConvertible.

Any ideas?

Thanks

Yes and No.

No because you cannot Directly. Anything that databinds to a datagrid must
implement IList, and DataReader does not.

Yes, because you could populate your own object using a datareader that
implements IList.
