In his posting on Command Bar knowledge Mr Durrow states, "A new 'mini' Command Bar is shown above each form Sub Grid showing only the 'Add' and 'Open Associated Sub Grid' buttons with the Delete button shown next to each record."
He goes on to mention that this mini Command Bar is not customisable beyond over riding the buttons (how?)
What about the Delete button next to each record? Can I get to that? Commandeer the functionality? Replace the icon?
In a supported manner, of course!
