Since Alex cannot help me, can anyone else help me get to the illusive "listItems" object that a datagrid has? I see it's related to the ListData object and have tried several ways of trying to get to the object with no luck.
Alex's reference here to "Subclassing" is stumping me. When I look around for how to "subclass" it's simply extending the object. But that doesn't seem to expose any of the underlying private objects. Seriously, I'm really stumped on this one. It's just some principle I'm missing, obviously. I have created new datagrid extending objects, tried using casts through interfaces, just about anything I could think of. I'd like to learn this if possible. Please help!
