RE: [flexcoders] Re: Okay, I know this is possible...DataGrid to Tree
preventDefault() is needed to prevent the base class from putting up default feedback. You may need to override dragDrop event to map the DG data to tree data.

I haven't posted to this thread in a while but I still havn't fixed it.

While it is not exactly what you want, there is an example with runnable code in the updated Drag and Drop doc on the Flex Doc Blog that shows how to drag from a List to a DataGrid. It requires that you modify the dragged data as part of the drop to make it compatible with the DataGrid. http://blogs.adobe.com/flexdoc/drag_and_drop/ One thing to remember when writing the dragEnter handler is that for all controls except for Tree, the format string is items and the items implement the IDataProvider interface.
