Al hacer click en una celda te manda info de fila y columna, ejemplo de la ayuda:
// Set up sample data.
my_dg.dataProvider = [{name:"Clark", score:3135}, {name:"Bruce", score:403}, {name:"Peter", score:25}];
// Create listener object.
var dgListener:Object = new Object();
dgListener.cellPress = function(evt_obj:Object) {
var cell_str:String = "("+evt_obj.columnIndex+", "+evt_obj.itemIndex+")";
trace("The cell at "+cell_str+" has been clicked");
};
// Add listener.
my_dg.addEventListener("cellPress", dgListener);
