Yves, THANK YOU , THANK YOU , THANK YOU... life is good. Worked like
a champ. I had never done the mx_internal piece, great pointer thank
you very much.
Here is a sample of the function I created, David I hope this helps:
private function dropData( event:DragEvent ) : void
{
var parent:String =
event.dragInitiator.mx_internal::_dropData.parent.label;
var childParent:String = item.parentComp;
if(parent == BOXC){
trace(moved through the match);
}else{
event.preventDefault();
trace(moved out of the match);
}
}
Put this in your import statement area:
import mx.core.mx_internal;
use namespace mx_internal;
Thanks again Yves!

When a drag drop operation occurs on a tree, the drag drop handlers
call the public calculateDropIndex() function. This function stores all
the properties that you want in an mx_internal variable called _dropData
of Object data type.
So, make sure that your class import and use the mx_internal namespace
and attach a listener to the tree's dragDrop event. In the event
handler, look up the _dropData variable and specifically the parent
and index properties. If this drop operation should not be allowed,
call the preventDefault() method on the event.
That should do the trick.

Subject: [flexcoders] Tree Control Drag and Drop Help
This is a two part question.
1 - How can I keep a child from being dropped outside of it's parent?
I want to be able to drag and drop within a nodes parent.
2 - How do I get a handle on the new index of the node that has been
dropped.
I can get the current index, the parents name, but not the location it
was dropped.
I am using an ArrayCollection to populate the tree, using the children
attribute to create the child nodes. I am stuck with having to use
the ArrayCollection.
Any pointers would be great.
