I'm new to GSX 3 and trying to figure out how checkbox selection events inn a Grid work in the new model. I just want to get notified on each checkbox check/uncheck change so I can set a boolean property on the model that was clicked. I don't want to get a list of all selected items like the SelectionChangedEvent seems to provide. This was really easy in the 2.x model but I'm not grasping it from the examples. Ther checkbox grid example doesn't seem to handle any events. Thanks for any help.
