How to refresh a grid on version 2.0

Please,

On version 1.0, i'm use this:

Obj.refresh();

And on version 2.0? What changed?

Thanks!

Nothing, refresh() is still the same. There are great examples that came with the 2.0 toolkit. I suggest that you read the source code to see the new things that you can do and the changes in syntax between 1.0 and 2.0. Expect to spend at least an hour looking through all the examples and the ones that are also in the Quickref directory.
