Possible to hide grid column programmatically?

[Jangla]

I have a toolbar on a grid that has a button to which I would like to attach some code that will hide and show various columns in the grid.

Can't find any code that would suggest this is possible - is it?

Which class is tasked with the managing of columns?

Ah - found it! Thanks for the pointer Animal :)
