Grid EditorFieldGroup

Hi,
is there a way to handle "EditorFieldGroup" "display or attached" event in order to disable/enable fields depending on user's roles and some row's props?
This is because in the grid, there could be rows where the user can edit some cols and in other rows cannot but may be able to edit other fields.

Or can you point me to the right direction to achieve this?

thank you

Easiest way is set own editor fieldgroup and override configureField() method in it,
