Initial sorting in grid view

Hello,
Cold somebody point to how to set a initial sorting of data displayed in grid view???
I have flowed the tutorial "Manage Events-Resources in a CMP" and successful set it up. I want to see my resources listed from last one to first one (DESC). So having them listed according to the ID - (DESC not ASC)

on the tab MIGXdb-Settings there should be a field 'getlist defaultsortdir'

put 'DESC' into it

Thanks Bruno for clearing this out. Now it works as I want!
You did a great job developing this add an. It gives so much new possibilities!
Thank You
