Data Grid? I'm just tryin to amke a simple button column extension and keep
getting an exception on the paint.

Tried everything... anyone have some experience with this?

Already contacted Jan, but don't know if he is checking messages right now
(I think its 7pm his time, not sure though...)

I hope he can, I really like this grid, and don't want to do my own
implementation of a button. =)

Mhm... I never said that I would be able to help, but without any
information on the exception its even harder.
I am also full curiosity watching his answer.
LOL.

Give some time to Herfried, otherwise you can maybe use this page from Jan.

HI CJ, I am sure

I changed your message only and now it looks if I am not sure about that
