Okay i am trying to load the ID3 tag information into a data grid. Now from the awsome documentation, i figured out how to make this happen. Now I want it to change when I load a new song. This is the AS i am using, can anyone help. I think that I need to add an even listener to listen for the change on mySound_sound but not sure how to do this for it trigger the change on the data grid. Thanks.
