Answer 1

I think there's a .disable() function on datagrids, or you can use return false; so that it won't proceed.

Answer 2

Try this.contains(child:DisplayObject) It Determines whether the specified display object is a child of the DisplayObjectContainer instance or the instance itself. The search includes the entire display list including this DisplayObjectContainer instance. Grandchildren, great-grandchildren, and so on each return true.
