What I meant was having a function on the Object added to the grid, not
on the grid itself. Something like this:
public class CustomGrid extends DataGrid {
(...)
override public function addElement(value:Object):void {
super.addElement(value);
executeCustomCode(value);
}
public function executeCustomCode(value:Object):void {
try {
value.customFunction();
}
catch(error:TypeError) {
// ADD YOUR DEFAULT CODE HERE
}
}
}
The syntax is not correct but it gives you the big picture. To improve
this you could had a listener on /added/ to the dataProvider that
triggered the executeCustomCode function.
Hope this helps,
Frederico Garcia
