Sreenivaas,
Nice blog and nice examples.. I think Flex 3 is far better that Flex 2. at this moment we have been using Flex 2 as 3 is in Beta, but kudos to you for a nice blog and examples.
This is great! Is there a way to enable drag and drop between the folders? I have tried various things but can't get that to work.

If we set dragEnabled, dropEnabled and dragMoveEnabled to true on ADG we should be able to drag drop items between folders. But we also need to add a event listener to the drop event and adjust the parentTask attribute etc to cater for the drag-drop.
Do you have an example of that? I have tried but I cannot get it to work.
